Thanks Michael,
I general my queries could be more complex than the
example I outlined earlier, so I do need to use the
Query Parser. Hence, PerFieldAnalyzerWrapper and
KeywordAnalyzer seemed to do the trick for me.
PerFieldAnalyzerWrapper analyzer = new
PerFieldAnalyzerWrapper(new StandardAnalyzer());
analyzer.addAnalyzer("PROJECT", new
KeywordAnalyzer());
QueryParser parser = new QueryParser(defaultField,
analyzer);
