Michael Gibney created LUCENE-8544:
--------------------------------------
Summary: In SpanNearQuery, add support for inOrder semantics
equivalent to that of (Multi)PhraseQuery
Key: LUCENE-8544
URL: https://issues.apache.org/jira/browse/LUCENE-8544
Project: Lucene - Core
Issue Type: Improvement
Components: core/search
Reporter: Michael Gibney
As discussed in LUCENE-8531, the semantics of phrase search differs among
{{(Multi)PhraseQuery}}, {{SpanNearQuery (inOrder=true)}}, and {{SpanNearQuery
(inOrder=false)}}:
* {{(Multi)PhraseQuery}}: incorporates the concept of order, and allowsÂ
negative offsets in calculating slop/edit distance
* {{SpanNearQuery (inOrder=true)}}: incorporates the concept of order, and
does _not_ allow negative offsets in calculating slop/edit distance
* {{SpanNearQuery (inOrder=false)}}: does not incorporate the concept of order
at all
This issue concerns the possibility of adjusting {{SpanNearQuery}} to be
configurable to support semantics equivalent to that of {{(Multi)PhraseQuery}}.
