+1 to the proposal
> TextField.analyzeMultiTerm should not throw exception when analyzer returns

> Key: SOLR-6613
> URL: https://issues.apache.org/jira/browse/SOLR-6613
> Project: Solr
> Issue Type: Bug
> Components: Schema and Analysis
> Affects Versions: 4.3.1, 4.10.2, 6.0
> Reporter: Bruno Roustant
> Priority: Major
> Attachments: TestTextField.java
>
>
> In TextField.analyzeMultiTerm()
> at line
> try {
> if (!source.incrementToken())
> throw new SolrException();
> The method should not throw an exception if there is no token because having
> no token is legitimate because all tokens may be filtered out (e.g. with a
> blocking Filter such as StopFilter).
> In this case it should simply return null (as it already returns null in some
> cases, see first line of method). However, SolrQueryParserBase needs also to
> be fixed to correctly handle null returned by TextField.analyzeMultiTerm().
> See attached TestTextField for the corresponding new test class.
