Short answer: it depends.
Questions for you to answer:
What field type and analyzer did you use during indexing? What
analyzer used with QueryParser? What does the generated Query.toString
return?
in both cases SimpleAnalyzer
QueryParser.parse("\"abc\"") throws an exception and i can't see what does
Query.toString return in this case
This is clean and green for me:
public void testAbc() throws ParseException {
Query query = QueryParser.parse("\"abc\"", "field", new SimpleAnalyzer());
assertEquals("abc", query.toString("field"));
}
Either you're using an old version of Lucene that is broken in this regard (I'm at CVS HEAD) or something else is fishy.
Note that a single term in quotes is optimized into a TermQuery, not a quoted PhraseQuery in the assert above.
what analizer should i use if i want to execute folowing queries: simple key word seach (+bush -president , etc) range queries including " characters in searching values
Ranges with spaces in them doesn't work. It is for single term ranges, not phrases that were tokenized. If you indexed the entire "phrase" as a single term (Field.Keyword), then you could do an API RangeQuery, but QueryParser won't be happy.
QueryParser syntax is documented on the Lucene website if you need assistance with the type of syntax it supports.
