The search is case-sensitive. It will return numeric if returnsubexpressions is false and a struct of arrays named "len", "match" and "pos" when returnsubexpressions is true. ## Method Signature ``` reFindNoCase(reg_expression=[string], string=[string], start=[integer], returnSubExpressions=[boolean], scope=[string]) ``` ### Arguments | Argument | Type | Required | Description | Default | | ---------------------- | --------- | -------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------- | | `reg_expression` | `string` | `true` | The regular expression to search for | | | `string` | `string` | `true` | The string to serach in | | | `start` | `integer` | `false` | The position from which to start searching in the string. Default is 1. | `1` | | `returnSubExpressions` | `boolean` | `false` |

True: if the regular expression is found, the first array element contains the length and position, respectively, of
the first match. If the regular expression contains parentheses that group subexpressions, each subsequent array
element contains the length and position, respectively, of the first occurrence of each group. If the regular
expression is not found, the arrays each contain one element with the value 0. False: the function returns the
position in the string where the match begins. Default.

| `false` | | `scope` | `string` | `false` | "one": returns the first value that matches the regex. "all": returns all values that match the regex. | `one` | ## Examples ## Related * [Ascii](/boxlang-language/reference/built-in-functions/string/ascii.md) *
