That was my thought. I'll make this change soon.

I'd lean toward (2) since most searches won't use these fields.

Sounds good.

OK. It seemed to me that the behavior needed to be different when answering a
direct search (non-persist) vs when add/mod/del were sending out a persist
response, but I didn't spend too much time trying to understand it. I was
particularly unsure about when the actual search attrs were being used, vs
the uuid_attr or null_attr. I believe in most cases rs.sr_attrs only needs to
be set once, at the top of the search loop. It's only the alternating between
null_attr and search attrs that still needs to be managed.

Yes.

Go ahead. I think the only other change I'll make here is to move
rs.sr_nentries into the rep_search_s and have send_search_entry increment
this itself. I can patch that change in whenever, no special dependencies
there.
