term position in phrase query using queryparser

[Tim Williams <wi...@gmail.com>]

Is there a syntax to set the term position in a query built with
queryparser?  For example, I would like something like:

PhraseQuery q = new PhraseQuery();
q.add(t1, 0);
q.add(t2, 0);
q.setSlop(0);

As I understand it, the slop defaults to 0, but I don't know how to
search for basically two tokens at the same term position using the
queryparser syntax.

Thanks,
--tim

I don't think this is available from the QueryParser. You could make a  
subclass that does this for the phrase query syntax. So if you have  
something like "term1 term2" then you can build your own Query and  
return it, but then you can't use phrase queries anymore... Either  
that or do your own parser...
