interpreted as prohibited clauses
I think all you need to do is escape the hyphen, or have you tried that
already?

hello
environment: solr 3.5
problem statement:
i have a requirement to search for part numbers that start with a dash /
hyphen.
example q= term: *-0004A-0436*
example query:
http://some_url:some_port/some_core/select?facet=false&sort=score+desc%2C+rankNo+asc%2C+partCnt+desc&start=0&q=*-0004A-0436*+itemType%3A1&wt=xml&qt=itemModelNoProductTypeBrandSearch&rows=4
what is happening: query is returning a huge results set. in reality
there
is one (1) and only one record in the database with this part number.
i believe this is happening because the dash is being interpreted by the
query parser as a prohibited clause and the effective result is, "give me
everything that does NOT have this part number".
how is this handled so that the search is conducted for the actual part:
-0004A-0436
thx
