Shawn Heisey commented on SOLR-16359:
-------------------------------------
Jira is not the correct replace for support requests. Those should go to the
mailing list, IRC channel, or slack channel.
[https://solr.apache.org/community.html]
A reindex is required because you changed the index analysis part of the
fieldType. The existing documents in the index before your schema change went
through a different tokenizer than the new documents, so the query could not
work on them until they were reindexed.
If you need further support on this, please use one of the methods mentioned.

> In my existing Solr core index. I am trying to get relevant search results
> working with or without the words, hyphens.
> Here is the query example for `like` clause: `q=Address : ( *{*}5-6*{*} {*})
> AND SID : ( *{*}{*}584*{*} *) AND City : ( ** *brentwood ** )`
> In the configuration file `/conf/managed-schema.xml` I changed the tokenizer
> to `solr.KeywordTokenizerFactory` from the default tokenizer
> `solr.StandardTokenizerFactory` on general text filed `text_general`.
> <fieldType name="text_general" class="solr.TextField"
> positionIncrementGap="100" multiValued="true">
> <analyzer type="index">
> <tokenizer class="solr.KeywordTokenizerFactory"/>
> <filter class="solr.StopFilterFactory" ignoreCase="true"
> words="stopwords.txt" />
> <filter class="solr.LowerCaseFilterFactory"/>
> </analyzer>
> <analyzer type="query">
> <tokenizer class="solr.KeywordTokenizerFactory"/>
> <filter class="solr.StopFilterFactory" ignoreCase="true"
> words="stopwords.txt" />
> <filter class="solr.SynonymGraphFilterFactory"
> synonyms="synonyms.txt" ignoreCase="true" expand="true"/>
> <filter class="solr.LowerCaseFilterFactory"/>
> </analyzer>
> </fieldType>
> The above configuration is working fine for new `core` index data. But it is
> not working on the existing `core` index. I had to delete the old index data
> and reindex from the scratch. *Is there any way to work reindex the data
> without delete the old data?*
