Does the default operator affect phrase searching?
I'm having a problem with doing a phrase search of "david pdf".
When I search for just "david", I get 7 hits. When I search for "pdf"
I get 73 hits. On a legacy system, searching for "david pdf" I get
78 hits. And on Solr (1.4 - one of the nightly builds) - when searching
for "david pdf" I get 0 hits. I have the defaultOperator for my schema
set to AND - could this be causing the problem?
When I set {!lucene q.op=OR} in the query, I still get zero hits.
Suggestions? Is there any way to debug *why* something didn't hit?
Or dump out what is contained in the index for one of the records?
Thanks.

Sorry, but at the moment - I don't think I'm at liberty to say.
My problem was that somewhere along the way I picked up the mis-understanding
that I could do a phrase search like Text:"david pdf" and Solr/lucene would pick up
all documents that hit the field Text with either 'david' or 'pdf'. Now, I'm just doing the
query as something like Text:"david" OR Text:"pdf". This seems to work as expected,
and I'm getting 79 hits (it's ok to be one better than before - I imagine I'm doing
a little more indexing with Solr than legacy X).

Yes, it does - thanks!
Back to translating legacy search queries into Solr search queries. :)

Hi Dan,
Phrase search (ie using quote) in Lucene does exact match or your expression
so if you type ["david pdf"] (brackets are there to limit the query in my
mail only) the system search for a document that contain the term 'david'
and the term 'pdf' separated by a space (well in the classic case, I suppose
you don't have a specific query parser). So since your corpus does not
contain any document with "david pdf" results are empty. In any case, the
defaultOperator have nothing to do with this. It only occur if you do a
query like ["david pdf" toto] then it will be interpreted as ["david pdf" OR
toto] (given is is the default operator)
I don't know which other legacy system you also used, but this may be a
complete different query syntax and so quote are not interpreted in the same
way.

Is "pdf" inside the file or part of the file name?
What legacy system? I've helped write a couple of them. Some systems,
like Ultraseek, add parts of the filename as searchable text.
