When supplying tags for timew summary, only entries containing all of the tags specificed are shown. I propose possibility for or'ing them instead/aswell.

CURRENT:

Entry 1 has keyword A, B Entry 2 has keyword B, C

timew summary A B matches entry 1 timew summary B A matches entry 1 timew summary B matches both timew summary A C matches neither timew summary C A matches neither

PROPOSED:

Entry 1 has keyword A, B Entry 2 has keyword B, C

timew summary A B matches entry 1 timew summary B A matches entry 1 timew summary B matches both timew summary A C matches both timew summary C A matches both

What you described is inconsistent even though no details were specified. The 4th filter is this:

timew summary A C

and you want it to match both items, because tag A is in item 1, and tag C is in item 2. That result can only come about if the filter A C is interepreted as A or C. But if that's the meaning, then the first two filters:

timew summary A B
timew summary B A

Would match both records, because of the presence of B in both intervals. So I don't know what your specific rules were, but it's not intuitive. Could you elaborate on the syntax proposed?

Secondly, if the or capability is needed, then I would only implement and (which is implicit), xor and not, and of course the necessary precedence operators ( and ), so that we have proper algebraic expressions, just like Taskwarrior.

Yes of course you are right about the inconsistency. Sorry about that. In the "PROPOSED" all the alternatives would match both.

Concerning Taskwarrior expressions, you mean these, I presume: https://taskwarrior.org/docs/filter.html

... I think that sounds like a good angle.

I would also propose that it should be possible to search hierarchically for projects, so that "Parent" would match "Parent.child"

I agree that a full-featured filtering mechanism is desirable, and should match Taskwarrior style filters.
