[jira] [Updated] (SOLR-6468) Regression: StopFilterFactory doesn't
work properly without enablePositionIncrements="false"
[ https://issues.apache.org/jira/browse/SOLR-6468?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Alexander S. updated SOLR-6468:
-------------------------------
Description:
Setup:
* Schema version is 1.5
* Field config:
{code}
<fieldType name="words_ngram" class="solr.TextField" omitNorms="false" autoGeneratePhraseQueries="true">
<analyzer>
<tokenizer class="solr.PatternTokenizerFactory" pattern="[^\w]+" />
<filter class="solr.StopFilterFactory" words="url_stopwords.txt" ignoreCase="true" />
<filter class="solr.LowerCaseFilterFactory" />
</analyzer>
</fieldType>
{code}
* Stop words:
{code}
http
https
ftp
www
{code}
So very simple. In the index I have:
* twitter.com/testuser
All these queries do match:
* twitter.com/testuser
* com/testuser
* testuser
But none of these does:
* https://twitter.com/testuser
* https://www.twitter.com/testuser
* www.twitter.com/testuser
Debug output shows:
"parsedquery_toString": "+(url_words_ngram:\"? twitter com testuser\")"
But we need:
"parsedquery_toString": "+(url_words_ngram:\"twitter com testuser\")"
Complete debug outputs:
* a valid search: http://pastie.org/pastes/9500661/text?key=rgqj5ivlgsbk1jxsudx9za
* an invalid search: http://pastie.org/pastes/9500662/text?key=b4zlh2oaxtikd8jvo5xaww
The complete discussion and explanation of the problem is here: http://lucene.472066.n3.nabble.com/Help-with-StopFilterFactory-td4153839.html
I didn't find a clear explanation how can we upgrade Solr, there's no any replacement or a workarround to this, so this is not just a major change but a major disrespect to all existing Solr users who are using this feature.
