Hi Andrew, Thanks for the reply. I tried the query, but it produced an error “invalid regular expression: quantifier operand invalid”. Also, what would be the regular expression if you want to check whether all the words were in the field where you had say 10 words/phrases you wanted to check for? __ From: A.

I can’t figure out how to search myfield for all instances which contain “text1” AND “text2”. In other words | is the OR operator. What is the AND operator. Tried + and whilst that executes, it doesn’t return matching fields. Thanks Mark __
