Search Function Usage and Instance
In Excel, the STAR function is used to find the position of a specified text character in a string. The grammar structure is STAR (find_text, within_text, (start_nums)), where find_text is required and is the text to be found. Wildcards (question marks?) can be used. Match any single character, star * matches any string of characters. To find the real question mark or star, you need to type the wave character ~ before the character. Within_text is required, it is the text that contains the text to be found;start_nam is the character number in within_text to start the search. When omitted, it is assumed to be 1. If find_text is not displayed in within_text, return #DOWN! If start_nums is not greater than 0 or greater than within_text, it will also return #DOWN! Wrong value. For example, when looking for a phone number that starts with 18 and ends with 5 in the cells of the B2:B10 area, you can enter the formula = IFEND (Index(B:B, Smalll (IFEND (STAR (" 18*5",$B$2:$B$10)* Rows ($B$2:$B$10)," " ), Rows (1:1))," " ) in the selected C2 cell, press the ctrl-shift-enter combination key to calculate the array formula result, and then fill it down to the C10 cell to get the result.
In Python, the search() function is usually used to find any matches of a particular pattern in a string. For example, under the re module, when you define pattern = r"^\d+"(matching strings that start with numbers), for string1 = "123abc" and string2 = "abc123", you can use the search() function to find the matching pattern in the entire string. search_obj1 = re.search (pattern, string1) will output
Usage of the match function
The Match function is used as follows: 1. ** Syntactic structure **: Match(query value, data range, [matching method]). - ** Search Value **: A required value. It can be a numerical value or a cell reference to a number, text, or logical value. - ** Data Range **: Required parameters, the cell area to be searched. - ** Match Method **: An option. There are three modes: -1 (search for the smallest value greater than or equal to the search value, and the search value must be sorted in descending order), 0 (search for the first value equal to the search value, and the search value can be in any order, and there is no requirement for sorting), 1 (search for the largest value smaller than or equal to the search value. When the matching method is omitted, the effect is the same as 1, namely,"downward" matching. In this case, the search value must be sorted in ascending order). 2. ** Function **: Return the relative position of items in the array that match a specific value and order. For example, if you want to find the position of a particular value in a data area, you can use the Match function. 3. ** Real-world example **: - To find the exact number of values equal to 100 in the area B2 to B5, you can enter the formula "=Match (100, B2: B5,0)" in the cell and press the enter key to get the result. - To find the exact ranking of the score in cell E2 in the C2 to C8 area, the formula was "=Match(E2, C2:C8, 0)". - If you want to perform fuzzy matching (such as entering a score that is not in the grade sheet to find the corresponding ranking), you can change the third argument of the Match function to-1 (in this case, the query value must be sorted in descending order) or 1 (the query value must be sorted in ascending order). 4. ** Using with other functions **: - It can be used with the Index function to realize the automatic query function of the table. For example, first enter "=Match(E2,B2:B8,0)" in cell F2, then nest the Index function "=Index(C2:C8,Match(E2,B2:B8,0)", press the enter key to find the corresponding position of the employee, and when the employee's name is changed, the position will be automatically updated. - It can be used together with the Vlook-up function to make up for the shortcoming of the Vlook-up function that requires the column parameters to be modified every time it looks for data. For example, when the input is equal to the VLOOkUP+Match key, the third argument of the Vlook up function can be replaced by the Match function. After setting the parameters according to the corresponding rules, enter, and then fill to the right and down, you can query in batches. "Choose" was equally exciting.

Usage of the sample function
The sample function is used as: sample(x, size, replace = False, prob = nil). Where, x can be a matrix containing one or more elements or just a positive integral. When the length of x is 1, the sample is extracted from 1: x;size is a non-negative integral, representing the number of samples extracted from the population;replace represents whether there is a return sample;prob is the probability weight matrix used to obtain the elements of the matrix to be sample. Another usage was sample(list,k), which would first return a new list of length k. The new list would store the random k unique elements in the list. For example, it was more convenient to move some data in a file for training and testing sets or other useful places. "Choose" was equally exciting. Everyone was welcome to read it!

Introduction to the Function and Usage of the Martial Impartation Artifact
There were many kinds of magic tools in the martial arts teaching. The following were the functions and usage of some of the magic tools: ** 1. Coiling Dragon Staff ** 1. ** Function * - It was helpful in stimulating the middle section to exert force and the tip section to exert Quake Energy, thus achieving the effect of coiling the body and strengthening the bones and muscles. Through the coiling of the machine, the force of the attack could be strengthened, and it could also increase the integration of the body's joints, making the combined force more precise. Its unique soft connection structure can increase the compatibility between the instrument and the body. - The reason why the Coiling Dragon Staff's power had increased so much was due to the chain-like structure in its middle section. Ancient weapons with similar structures could be used to break a horse's legs. Moreover, the two-section structure made it foldable and easy to carry. 2. ** Usage * - At the beginning of the practice, the person carried the rod and walked. As the stiff force was removed, it became the rod carrying the person and finally reached the realm of being one with the rod. ** 2. Gate Sealing Formation (Dharmic Artifact of the White Bone Cave's Six Techniques)** 1. ** Function * - Space type magic tool, can deploy a certain array to form a protective shield that can isolate space. The radius of the protective shield is about one mile, and it can withstand a certain degree of attack (the upper limit is about the full-strength attack of a top martial artist). - Able to shift the target's position regardless of the target's will. In actual combat, it can continuously shift the position of its own members within the range of the array. 2. ** Usage * - It did not mention the specific operation method to deploy the magic circle, but it was known that it could move the target's position according to the user's wishes in battle. ** 3. Chaotic Cloud Mist (Dharmic Artifact of the White Bone Cave's Six Techniques)** 1. ** Function * - The magic tool was in the shape of a smoke rod. It could produce smoke that could invade the ears of others. The smoke would interfere with the mind of the person being cast to produce a control effect. When the smoke entered one's ears, it would produce a type of insect that was connected to the Outer Gods. Under Yuge Sothoth's gaze, the weak would self-destruct when they heard the whispers, and the slightly stronger ones would go crazy. The strong would be transformed into the followers of the Evil God if they failed to resist. Once their strength reached a certain level, they would be able to fight back against the Evil God without fear of the whispers. 2. ** Usage * - There was no mention of how to operate it to produce smoke and other details. ** 4. Wheel of Blood (one of the Six Techniques of the Cave of Bones)** 1. ** Function * - Attack-type magic tool, powered by blood, can launch a flying wheel to attack the enemy. It has a certain tracking ability but is not flexible enough. The flying wheel will split after being attacked or counterattacked. The user can restart the stopped flying wheel, and the more the attack, the more powerful it is. However, the demand for blood will also increase. 2. ** Usage * - The user needed to provide blood as a power source to launch the flywheels to attack. ** 5. Divine Self Finger Cuff (Magical Artifact of the White Bone Cave's Six Techniques)** 1. ** Function * - Support-type + site-type magical equipment had two main characteristics: one was that it had extremely high fire resistance, which could greatly reduce the fire attribute damage received; the other was that it could release the venue, the City of Bones. The user could freely walk through the City of Bones, and the City of Bones was a no-fly zone, so no one could fly. 2. ** Usage * - There was no mention of how to release the City of Bones and other details. ** 6. Thunder Mace ** 1. ** Function * - The main forging materials were thunder iron and mountain essence. Martial artists who mainly cultivated Yang energy, Yin energy, and thunder spells would have additional bonuses when using them. It can convert qi into lightning of similar attributes. After the user infuses qi into it, it can produce lightning attribute attacks. - However, there was a hidden danger. The user would obtain a lightning-attracting constitution and would be easily struck by lightning. Moreover, it would gradually numb the user's nerves. Long-term contact would make the sense of touch abnormally slow, affecting the control of one's own state in battle. Many users of the past would die from serious injuries after the battle. 2. ** Usage * - Inject your own qi into the lightning rapier and then strike. ** 7. Heavenly Benevolence Sword ** 1. ** Function * - The sword of the Dipper. It can be split into two swords to release the Dipper Star Palace-Heavenly Rooster.

How to use the search function
The search function is used to find the starting position of the specified search value in the string. The grammar is Search(find_text, within_text, start_nums), where find_text is the character to be found. Wildcards can be used in find_text, including question marks (?) To find the real question mark or star, you need to type a tilde (~) in front of the character;within_text is the text in which you want to find_text;start_numis the number of the character in within_text to start looking for. For example, in a table, you can use the search function by entering a formula in the cell, such as entering = STAR in cell B1.("Month",A1,1), the number displayed in the result indicates that the position of "Month" is located from the first character of the A1 cell string; enter = STAR (A3,A2) in the B2 cell, the number displayed in the result indicates that the content of the A3 cell is located in the position of the A2 cell content; enter = STAR in the B2 cell ("*",A2,1), because the star "*" can represent any string, it returns 1; in cell B2, enter = STAR ("~*",A2,1), if the argument find_text is a question mark or an star, add the "~" symbol and return the corresponding position. In addition, the search function can also be used for some complex operations, such as finding the position of the second specific character in the string (you need to set the start_nums parameters reasonably), counting the number of strings in a specific format (combined with other functions, such as the Count function), extracting a specific part of the content (combined with other functions, such as the Midb function), and so on.

Data Search Function Formula
The following are some common data search function formulas: ** 1. VLOOkUP Function ** 1. ** Function * - Finds the specified value in the first column of a table or array of values, and returns the value in the current column of the table or array. 2. ** grammar structure ** - =VLOOkUP(Search value, data table (search area), column number,(matching condition)) - For example, if the search area is B2:E10, the search name is in cell G3, and the assessment score is in column 2, the formula is =VLOOkUP(G3,B2:E10,2,False). - Note: - It could only be searched from left to right, but not in reverse. - The search value must be in the first column of the data table (search area), otherwise an error will be reported. - Special Usage: - When searching for multiple results, you can use VLOOkUP or array usage multiple times. For example, to find the employee's department, birthplace, and salary data, if the name was in the G2 cell, the search area would be A:E, the department would be in the fourth column, the birthplace would be in the fifth column, and the salary would be in the third column. The formula could be used multiple times: Department: = VLOOkUP (G2,A:E,4,0); birthplace: = VLOOkUP (G2,A:E,5,0); salary: =VLOOkUP(G2,A:E,3,0) Using the array usage formula: =VLOOkUP(G2,A:E,{4,5,3},0)(The new version has the array overflow function to directly obtain the result. Without this function, you need to first select the corresponding cell, press the three keys of the array, and press the command button.) - Search for the last record: When the data is a number, the formula is =VLOOkUP(9^9,A:A,1)(the first argument is 9 to the power of 9, you can also write other numbers larger than the number in column A, the fourth argument default fuzzy search); when the data is text, the formula is =VLOOkUP("seat",A:A,1); when the data is mixed, if the requirement is to return whatever the last data is, you need to use the LOOkUP function. - It is used for sum operations, such as the formula =SUM(VLOOkUP(B11,$A$2:$G$8,{2,3,4,5,6,7},0)). By modifying the third argument, query the column of each month, find the corresponding month data, and then sum. ** 2. LOOK UP Function ** 1. ** grammar ** - = look up (find the value in that column and return the result column). For example, to find the number of bananas, if the search value is in the D2 cell, the search area is A2:A5, and the result is B2:B5, the formula is =LOOkUP(D2,A2:A5,B2:B5). - When the data is mixed and the last data is to be found, the formula is =LOOkUP(1,0/(A:A<>""),A:A). ** 3. SUMIF Function ** 1. ** grammar ** - =sumif(condition column, sum condition, sum column). For example, if you want to ask for the number of oranges, if the condition column is A2:A5, the sum condition is in cell D2, and the sum column is B2:B5, then the formula is =SUMIF(A2:A5,D2,B2:B5). ** 4. DGET Function ** 1. ** grammar ** - =dget(data area, column number of the result to be found, search criteria). Note that when selecting data, you must also select the header. For example, if you want to find the data of lemons, if the data area is A1:B5, the result is in the second column, and the search condition is D1:D2, then the formula is =DGET(A1:B5,2,D1:D2). ** 5. DSUM Function ** 1. ** grammar ** - =dsum(data area, the name of the field that needs to find the result, and the search criteria). This function is a database function. All the data in the parameters need to include the header. For example, if you want to find all the data of apples, if the data range is A1:B5, the field name is in the E1 cell, and the search criteria is D1:D2, the formula is =DSUM(A1:B5,E1,D1:D2). ** 6. Summer Function ** 1. ** grammar ** - = sumproduct(first data area, second data area, third data area) and so on. For example, to find the number of apples, if the data area A2:A5 was judged to be equal to D2 (apple type), then multiplied by B2:B5 and then summed, the formula would be = SUMPRODOCT ((A2:A5 = D2)*B2:B5). ** 7. Index+Match Function Formula Combination ** 1. [Description] - It could be said to be an omnipotent screening and search combination. 2. ** grammar structure ** - =Index(Array result column,Match(search value, search area, 0)). For example, according to the employee's "name" to search for the corresponding "assessment results", if the search area is B2:B10, the search value is in the G3 cell, and the result column is C2:C10, first obtain the row number where the query value is through Match(G3,B2:B10,0), and then use the Index function to find the value of the corresponding row in the result column. The formula is =Index(C2:C10,Match(G3,B2:B10,0)). ** 8. XLOOkUP Function ** 1. ** Function * - Searching for a match in a range or array and returning the corresponding item through a second range or array. By default, an exact match is used. 2. ** grammar structure ** - =XLOOkUP(Find Value, Find Array, Return Array, No Value Found, Match Mode, Search Mode). Generally, you only need to set the first three functions. For example, if you want to check Zhao Fei's basic salary, if the search value is in cell G3, the search area is A2:A8, and the return area is D2:D8, then the formula is =XLOOkUP(G3,A2:A8,D2:D8). ** 9. TOCOL function (used to find data samples)** - When searching for data based on multiple conditions, such as searching for salaries based on departments and names, it could be used to compare multiple columns with the given conditions. If they were equal, the value of the corresponding column would be returned. The second argument could ignore the error value to obtain the correct result. It could also be used to list the list of personnel in each department. "Choose" was equally exciting. Everyone was welcome to read it!
