minimum string length for proximity search
Is there a minimum string length requirement for proximity search? For
example, would "a~" or "an~" trigger proximity search? The result
would be horrible if there is no such requirement.
Thanks,
Andy

We are trying to do proximity search for multi-terms and we don't care
the order of the terms. Therefore "term1 term2"~5 probably will not
get you "term2 term1" if both terms are long. So instead of applying
distance at the end, we apply distance to each word, "term1~2
term2~2". I am wondering if we should skip short words if it is not
done automatically by the engine.
Thanks,
Andy

Uhhhm, doesn't "term1 term2"~5 work? If not, why not?
You might get some use from
http://lucene.apache.org/java/2_4_0/queryparsersyntax.html
Or if that's not germane, perhaps you can explain your use case.
