Tomoko Uchida commented on SOLR-13593:
--------------------------------------
I have updated the pull request.
1. If both of "name" and "class" are specified, this redundancy does not cause
any error but warnings are emitted when loading the schema. In this case "name"
is given priority over "class". (In a future release "class" could be
deprecated so this behaviour makes sense to me, any comments?)
2. Added unit tests: for loading field types from schema.xml and creating
those via REST API.
LUCENE-8778 was backported with proper backwards compatibility (LUCENE-8911),
so I think we can expose this feature from 8.x minor releases. After the pull
request gets reviewed I'd like to commit the changes to the master and 8x
branch, then migrate default schema file(s) and the examples in Ref Guide.

> Key: SOLR-13593
> URL: https://issues.apache.org/jira/browse/SOLR-13593
> Project: Solr
> Issue Type: Improvement
> Components: Schema and Analysis
> Reporter: Tomoko Uchida
> Priority: Major
> Time Spent: 20m
> Remaining Estimate: 0h
>
> Now each analysis factory has explicitely documented SPI name which is stored
> in the static "NAME" field (LUCENE-8778).
> Solr uses factories' simple class name in schema definition (like
> class="solr.WhitespaceTokenizerFactory"), but we should be able to also use
> more concise SPI names (like name="whitespace").
> e.g.:
> {code:xml}
> <fieldtype name="myfieldtype" class="solr.TextField">
> <analyzer>
> <tokenizer class="solr.WhitespaceTokenizerFactory"/>
> <filter class="solr.KeywordMarkerFilterFactory" protected="protwords.txt"
> />
> <filter class="solr.PorterStemFilterFactory" />
> </analyzer>
> </fieldtype>
> {code}
> would be
> {code:xml}
> <fieldtype name="myfieldtype" class="solr.TextField">
> <analyzer>
> <tokenizer name="whitespace"/>
> <filter name="keywordMarker" protected="protwords.txt" />
> <filter name="porterStem" />
> </analyzer>
> </fieldtype>
> {code}
