Agoston,
If there is a reproducible scenario where search fails, you should open
a bugzilla so that it will be fixed. You're sure this isn't simply
being affected by things like choosing to search only in the enclosing
project rather than the whole workspace or by the fact that the regular
expression syntax you are using isn't the one Eclipse is recognizing?
There's a toolbar button on the search view that you can use to rerun
the search (F5), but I suppose you are saying this just fails to really
do a search, in which case, it should be easy to create a reproducible
bug report...

Hi Ed,
another interesting fact (this might be a clue): if I open a file that
contains the pattern but was not included in the search results (a missed
hit), then re-run the search, it will find that as well from then on (but
not the rest of the missed ones). It's as if it is some caching or
indexing problem...

Unfortunately it's *NOT REPRODUCIBLE*. It's a relatively huge project
we're working on (2000+ java files), and it only happens from time to time
undeterministically (as far as I'm concerned). The only deterministic
thing is once a specific search combination gives incorrect results, it
will return that same result the next time, too. (I have tried out
refreshing the results with F5, and it does re-execute the search - but
the result is the same incorrect one.)

*NO REGEX* included. Yes, usually I define a *WORKING SET* to search in,
but it does contain those files. However, I just tried it out setting the
scope to 'Workspace' - still only the reduced result set. (I have a case
right in front of me, so I'm able to experiment with the phenomenon.)

No, this is not the case. (See above.) F5 works correctly, the search
itself doesn't, and it's not reproducible.
Thanks,

Agoston,
I wonder if there might be clues in the Error Log that something is
failing? (I hate those hard to reproduce bugs both as a user and as a
developer wanting to fix them.)

I'm pretty sure there is no internal caching of search results.
Based on what you've said, my first suspicion is that you have files
that are being modified outside of Eclipse. If so, you need to make sure
to refresh the containing Project(s) in Eclipse in order for the
external changes to be detected. Eclipse does not, by default, monitor
for arbitrary changes to the file system, so it is possible some other
process has touched the files and Eclipse doesn't know about it yet.
Is that the case in your situation?
Eric
