Find Muti File Names

I'm doing a search of many drives using Collection. I did know but forgot how to list multiply values. If i remember I could list them all in the "Simple" Find that appears at bottom of "Lister", window.
Example:
*.dbf
*.mdf
*.dbt

Thanks for the help.

Do you mean turning on the Filter Bar with the * (asterisk) key?

No. any drive that has the following I need to see in the coll://Permit

Example *.dbf would find builder.dbf and permit.dbf
also *.dbt would find car.dbt, tree.dbt, house.dbt
*.mdf could find grass.mdf, desk.mdf,barn.mdf

I thought it used to work with a pipe in "Simple" mode
.dbf|.mdf|*.dbt

That don't seem to work.
Bob

*.(dbf|mdf|dbt)

Thanks.
Bob

It did work fine.
But I had no luck expanding on the search. I wanted to add the actual file names using the "Simple" mode.
Builder.(dbf|mdf|dbt)|City.(dbf|mdf|dbt)

I thought if I added the pipe it would work for me.
Bob

(Builder|City).(dbf|mdf|dbt)

I was expecting a rather complex solution. Thanks for making my day a lot easier! What can I say. Thanks for tacking the time.

No worries. The best rule to remember is whenever you have an OR (a pipe), it needs to be in brackets.
