Search doubled pawns in Scid database?

Sort:
oblivskep

Hi guys, I use Scid 4.6.4 on Linux Debian 10.
I want to search games where doubled pawns happened. In any column.
Should I do something in the Material/Pattern window, in the section Patterns?
Or in other words: How can I search in scid, positions/games where doubled pawns have occurred?
