Advanced Search Help

[glenviewjeff]

I still struggle with the advanced search. I want to accomplish this:

(Lineage Matches *A OR Lineage Matches *B OR Context equals C) AND ( Begin Date <= 11/30/08 OR Begin Date !Exists )

I laid it out like this, but I apparently am making a mistake:

Lineage Matches *A
OR Lineage Matches *B
OR Context equals C
AND Begin Date <= 11/30/08
OR Begin Date !Exists

Thanks!
Jeff
