Problem with search in Sublime Text 3


When searching for an expression like "add_filter( 'excerpt_length" I get the following error message:

-----Searching 1277 files for "add_filter( 'excerpt_length" (regex)

Unmatched marking parenthesis ( or (. The error occurred while parsing the regular expression fragment: 'rpt_length>>>HERE>>>'. in regular expression add_filter( 'excerpt_length

0 matches across 0 files-------

Any suggestions how to solve this problem would be greatly appreciated.

on the left side of search box there are few options/buttons i believe the very first option on the left is to do with regex.. (hover over to make sure it says regex & click it)..

alternatively use this:

add_filter( 'excerpt_length

to search.. there is a tutorial here about regex in python but same rules apply.. regex searching is more powerful
