Robert Muir updated LUCENE-3821:
--------------------------------
Description:
The general bug is a case where a phrase with no slop is found,
but if you add slop its not.
I committed a test today (TestSloppyPhraseQuery2) that actually triggers this
case,
jenkins just hasn't had enough time to chew on it.
ant test -Dtestcase=TestSloppyPhraseQuery2 -Dtests.iter=100 is enough to make
it fail on trunk or 3.x
was:
In upgrading from Solr 1.4 to Solr 3.5, the following phrase searches stopped
working in dismax:
"The Beatles as musicians : Revolver through the Anthology"
"Color-blindness [print/digital]; its dangers and its detection"
Both of these queries have a repeated work, and have many terms. It's not the
number of terms or the colon surrounded by spaces, because the following phrase
search works in Solr 3.5 (and Solr 1.4):
"International encyclopedia of revolution and protest : 1500 to the present"
With Robert Muir's help, we have narrowed the problem down to slop (proximity
in lucene QueryParser, query slop in dismax). I have included debugQuery
details for the Beatles search; I confirmed the same behavior with the
color-blindness search.
Solr 3.5: it fails when (query) slop setting isn't 0.

For debug purposes, we can consider the Solr document as:
<doc>
<str name="all_search">The Beatles as musicians : Revolver through the
Anthology</str>
</doc>
I can't attached the full SolrDoc as all_search is indexed, but not stored, and
I use SolrJ to write to the index from java objects ... plus our objects have a
zillion fields (I work in a library with very rich metadata and very exacting
solr fields). I have attached the Solr 3.5 schema and solrconfig, but they are
big and ugly for the same reasons.
For more details, see the erroneously titled email thread "result present in
Solr 1.4 but missing in Solr 3.5, dismax only" started on 2012-02-22 on
solr-u...@lucene.apache.org.

Summary: SloppyPhraseScorer sometimes misses documents that
ExactPhraseScorer finds. (was: search slop problem introduced somewhere
between Solr 1.4 and Solr 3.5)
