David Smiley commented on SOLR-12242:
-------------------------------------
Thanks for raising this issue. It's similar to LUCENE-7757 which is support
for the ComplexPhraseQParserPlugin; check that issue out. It's temping to pass
the live IndexSearcher to extractTerms but that's potentially dangerous if the
query contains wildcards – we *don't* want to extract all terms from a wildcard
query on the index reader.

> Key: SOLR-12242
> URL: https://issues.apache.org/jira/browse/SOLR-12242
> Project: Solr
> Issue Type: Bug
> Security Level: Public(Default Security Level. Issues are Public)
> Components: highlighter
> Affects Versions: 7.2.1
> Reporter: Andy Liu
> Priority: Major
> Attachments: TestUnifiedHighlighterSurround.java
>
>
> I'm attempting to use the UnifiedHighlighter in conjunction with queries
> parsed by Solr's SurroundQParserPlugin. When doing so, the response yields
> empty arrays for documents that should contain highlighted snippets.
> I've attached a test for UnifiedHighlighter that uses the surround's
> QueryParser and preprocesses the query in a similar fashion as
> SurroundQParser, which results in test failure. When creating a SpanQuery
> directly (rather via surround's QueryParser), the test passes.
> The problem can be isolated to the code path initiated by
> UnifiedHighlighter.extractTerms(), which uses EMPTY_INDEXSEARCHER to extract
> terms from the query. After a series of method calls, we end up at
> DistanceQuery.getSpanNearQuery(), where
> {{((DistanceSubQuery)sqi.next()).addSpanQueries(sncf)}} fails silently and
> doesn't add any span queries.
> Another data point: If I hack UnifiedHighlighter and pass in a live
> IndexSearcher to extractTerms(), highlighting works.
