We are launching a new version of our job board helping returning veterans find
a civilian job, and we chose Solr and Sunspot[1] to power our search. We really
didn't consider the power users in the HR world who are trained to use boolean
search, for example:
"Engineer" AND ("Electrical" OR "Mechanical")
Sunspot supports the Dismax request handler, which unfortunately does not
handle the query above properly. So we read about eDismax and that it was baked
into Solr 1.5. At the same time, Sunspot has switched from LocalSolr
integration to storing a geohash in a full-text searchable field.
We're having some problems with some complex queries that Sunspot generates:
INFO: [] webapp=/solr path=/select
params={fl=+score&start=0&q=query:"{!dismax+qf%3D'title_text+description_text'}Ruby+on+Rails+Developer"+(location_details_s:dngythdb25fu^1.0+OR+location_details_s:dngythdb25f^0.0625+OR+location_details_s:dngythdb25*^0.00391+OR+location_details_s:dngythdb2*^0.000244+OR+location_details_s:dngythdb*^0.0000153+OR+location_details_s:dngythd*^0.000000954+OR+location_details_s:dngyth*^0.0000000596+OR+location_details_s:dngyt*^0.00000000373+OR+location_details_s:dngy*^0.000000000233+OR+location_details_s:dng*^0.0000000000146)&wt=ruby&fq=type:Job&defType=edismax&rows=20}
hits=1 status=0 QTime=13
Under Dismax no results are returned for this query, however, as you can see
above with eDismax a result is returned -- the only difference between the two
queries are '&defType=edismax' vs '&defType=dismax'
Debug Output Solr 1.5 eDismax:

Debug Output Solr 1.5 Dismax:

My question is if you have any ideas why the query above returns a record that
doesn't match, in eDismax?
We are at a crossroads where we have to decide if we want to forge ahead with
Sunspot 1.2rc4 and Solr 1.5, or we may fall back to Sunspot 1.1 and Solr 1.4
until Solr 3.1/4.0 come out, hopefully with eDismax support and better location
search support.
I plan to do a blog posting on this issue when we figure it out, I'll give you
props if you can help us out :)
