If I have 5 fields I'd like to search with the same criteria, is there any shorter way of doing that instead of

"Field1='a' OR Field2='a' OR Field3='a'....Fieldn='a'"

Additionally, I would like to have multiple criteria

"(Field1='a' OR Field2='a' OR Field3='a'....Fieldn='a') OR (Field1='b' OR Field2='b' OR Field3='b'...Fieldn='b')"

Thanks a lot, I'm hitting 64k limits like there's no tomorrow here! :)
