# RIGHT\$1FIND
<a name="recipe-actions.functions.RIGHT_FIND"></a>

Searching right to left, finds strings that match a specified string from the source column or from a custom value, and returns the result in a new column. 

**Parameters**
+ `sourceColumn` – The name of an existing column.
+ `pattern` – A regular expression to search for.
+ `position` – The character position to begin with, from the right end of the string.
+ `ignoreCase` – If `true`, ignore differences of case (between uppercase and lowercase) among letters. To enforce strict matching, use `false` instead.
+ `targetColumn` – The name of the new column to be created.
