Parameters

Sr.No.	Parameter & Description
1	find_text The text that you want to find. You can use the wildcard characters question mark (?) and asterisk (*) in find_text. A question mark matches any single character and an asterisk matches any sequence of characters. If you want to find an actual question mark or asterisk, type a tilde (~) before the character.
2	within_text The text in which you want to search for find_text, or a column containing text.
3	start_num Optional. The character position in within_text at which you want to start searching. If omitted, default is 1.
4	NotFoundValue The value that should be returned when find_text is not found in within_text. This can be any specific integer or BLANK ().

Return Value

An integer, or Blank if specified as NotFoundValue.

Remarks

• DAX SEARCH function is case insensitive. Searching for "N" will find the first occurrence of 'N' or 'n'.

• DAX SEARCH function is accent sensitive. Searching for "á" will find the first occurrence of 'á' but not any of the occurrences of 'a', 'à', or the capitalized versions 'A', 'Á'.

• You can use the SEARCH function to determine the location of a text string within another text string, and then use the MID function to return the text, or use the REPLACE function to change the text.

• If find_text cannot be found in within_text, DAX SEARCH function returns NotFoundValue, if given. If omitted, returns #ERROR.

• Nulls in within_text will be interpreted as empty strings.

Example

= SEARCH ("Yes", "Yesterday",, BLANK()) returns 1. 
= SEARCH("yes","Yesterday") returns 1. 
= SEARCH ("no", "Yesterday",, BLANK()) returns (blank). 
= SEARCH("no","Yesterday") returns #ERROR. 
= MID("Yesterday",SEARCH("day","Yesterday"),2) returns da. 
= REPLACE("Yesterday",SEARCH("day","Yesterday"),3,"fff") returns Yesterfff.
