Christine Poerschke updated SOLR-10957:
---------------------------------------
Attachment: SOLR-10957.patch
Attaching simpler alternative patch, getCore() returning null can be avoided by
calling getSchema() instead.
----
Background/Context:
How might the
[SolrCoreParser|https://github.com/apache/lucene-solr/blob/master/solr/core/src/java/org/apache/solr/search/SolrCoreParser.java]
be used _without_ a SolrCore you might ask?
* SolrCoreParser extends the Lucene
[CoreParser|https://github.com/apache/lucene-solr/blob/master/lucene/queryparser/src/java/org/apache/lucene/queryparser/xml/CoreParser.java]
i.e. the core part of the name has nothing to do with solr cores.
* [Flax|http://www.flax.co.uk/]'s
[Luwak|https://github.com/flaxsearch/luwak/blob/master/README.md] has a
[MonitorQueryParser|https://github.com/flaxsearch/luwak/blob/master/luwak/src/main/java/uk/co/flax/luwak/MonitorQueryParser.java]
interface and a
[LuceneQueryParser|https://github.com/flaxsearch/luwak/blob/master/luwak/src/main/java/uk/co/flax/luwak/queryparsers/LuceneQueryParser.java]
implementation of that interface.
* If a MonitorQueryParser implementation used the SolrCoreParser then it might
do so _without_ a SolrCore (but with an IndexSchema and a SolrResourceLoader).
