[jira] [Resolved] (SOLR-2510) Proximity search is not symmetric

["Hoss Man (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/SOLR-2510?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Hoss Man resolved SOLR-2510.
----------------------------

    Resolution: Not A Problem

This is the expected behavior for Phrase queries.

"slop" is specified as an edit distance...
http://lucene.apache.org/java/2_9_1/api/core/org/apache/lucene/search/PhraseQuery.html#setSlop%28int%29

These two queries are not equivalent...

{noformat}
  "WORD_D WORD_G"~3
  "WORD_G WORD_D"~3
{noformat}

the order of the terms as specified in the PhrasQuery matters for determining the edit distance.

>                 URL: https://issues.apache.org/jira/browse/SOLR-2510
>             Project: Solr
>          Issue Type: Bug
>          Components: search, web gui
>    Affects Versions: 3.1
>         Environment: Ubuntu 10.04
>            Reporter: mark risher
>
> The proximity search is incorrect on words occurring *before* the matching term. It matches documents that are _less-than_ N words before and _less-than-or-equal-to_ N words after.
> For example, use the following document:
>    {{WORD_A WORD_B WORD_C WORD_D WORD_E WORD_F WORD_G}}
> *Expected result:* Both of the following queries should match:
> 1) {{"WORD_D WORD_G"~3}}
> 2) {{"WORD_G WORD_D"~3}}
> *Actual result:* Only #1 matches. For some reason, it thinks the distance from D to G is 3, but from G to D is 4.
