You are getting the correct query as far as QueryParser is concerned.

Thanks very much for explanations, yes, there
is no linear relation when searching a keyword
which is only in a few docs.

Ok,
This is the method that adds the aliases, it is located in my SynonymFilter:
private void addAliasesToStack(Token token)
{
String[] synonyms = engine.getSynonyms("contents",
token.termText());
if (synonyms == null)
{
return;
}
Just took a quick peak at the MultiPhraseQuery toString() and it does
indeed wrap the query in quotes (it also puts in the parenthesis). You
are generating a MultiPhraseQuery. Is that not your intent?. The
QueryParser will generate a MultiPhraseQuery when more than one token
with different posi
It does not work.
Even with the synonyms indexed it is not found.
That's why my guess was to remove the "" but I dont know how.

a query like

That might be the correct representation of a MultiPhraseQuery. So does
your query work anyway? It's just that you cannot use QueryParser again to
parse this output (similar to some other queries like SpanQue
Sounds a very simple and typical use case for a product catalog

So if your text contains "wind" it is not found by the query that prints as
content:"(wind window)"? Then I suggest you post a small test case that
shows this problem. As Chri
Sorry, I forgot to include this information:
Doing:
token.setPositionIncrement(0);
It returns
content:"(wind window)"
With:
token.setPositionIncrement(1);
Returns:
content:"wind window"

a search process has to do usually two thinks. First it has to find the

What exactly did you measure, only the search() or also opening the
