I'm having trouble making other that one word queries.
For example "language <any other words here>" gives same result,
regardless of the other words.
Using quotes "\"some query\"" returns no results.
So I would like to make "fuzzy" multiword queries where for example
"language technology" returns different results that "language management"
And also to query "\"language technology\"" which should return exact
matches.
I'm using latest Jena with AnalyzingQueryParser, which gives warning
WARN TextIndexLucene :: Deprecated query parser type
'AnalyzingQueryParser'. Defaulting to standard QueryParser
Also tried other parsers.
