[O] How to filter agenda for Word1 OR Word2?

[Martin Beck]

I have a search result (created by a search agenda C-C a s) and I want to narrow it down further with additional criteria.

I tried to use the "=" key for "Narrow to entries matching regexp", but I did not find out how to combine several terms in here.

 

As long as I only enter one word, it works. But if I want to filter for criteria like

 

Word1 OR Word2

or (Word1 OR Word2) AND Word3

or (Word1 OR Word2) AND NOT (Word3 OR Word4)

 

I get no results just by entering

e.g. Word1|Word2

or Word1&Word2

 

I'm sure this is trivial, but I'm not an expert in regular expressions and currently don't see how to solve that.

:-(

 

Thanks a lot and kind regards
