Brad Sumersford created SOLR-12532:
--------------------------------------
Summary: Slop specified in query string is not preserved for
certain phrase searches
Key: SOLR-12532
URL: https://issues.apache.org/jira/browse/SOLR-12532
Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Components: query parsers
Affects Versions: 7.4
Reporter: Brad Sumersford
Note: This only impacts specific settings for the
WordDelimiterGraphFilterFactory as detailed below.
When a phrase search is parsed by the SolrQueryParser, and the phrase search
results in a graph token stream, the resulting SpanNearQuery created does not
have the slop correctly set.
h4. Conditions
- Slop provided in query string (ex: ~2")
- WordDelimiterGraphFilterFactory with query time preserveOriginal and
generateWordParts
- query string includes a term that contains a word delimiter
h4. Example
Field: wdf_partspreserve
-- WordDelimiterGraphFilterFactory
---- preserveOriginal="1"
---- generateWordParts="1"
Data: you just can't
Search: wdf_partspreserve:"you can't"~2 -> 0 Results
h4. Cause
The slop supplied by the query string is applied in
SolrQueryParserBase#getFieldQuery which will set the slop only for PhraseQuery
and MultiPhaseQuery. Since "can't" will be broken down into multiple tokens
analyzeGraphPhrase will be triggered when the Query is being constructed which
will return a SpanNearQuery instead of a (Multi)PhraseQuery.
