List contains function, does it work?

Does the contains function work for lists?

for instance

Fetch_Records = Form1 [multi_select_lookup_field.contains(Record_ID)];

It seems this script statement is not functional.

if it doesn't work, what would be the simplest workaround?

The help section on this topic (see below) is not clear. According to it, we need two parameters, list.contains(str1 , str2) ?

thanks for the help.
