Queries on search fields with analyzers that don’t tokenize on whitespace (e.g. untokenized fields or when using KeywordTokenizer) seem to get tokenized at query time. This is probably caused by the QueryParser in use. This causes missing and unwanted search results.

The query ‘Some Labeling’ on untokenized field scheme.name gets parsed to:

+((scheme.name:Some) (scheme.name:Labeling))

Where it should be

+(scheme.name:Some Labeling)
