Subject Re: ParseQuery with quotes
Date Tue, 20 Dec 2005 21:14:13 GMT
Ok, I understand the .toString() part.

But, if I have some 19" in the text of these items, and I do a search with
19", that has been escaped before parsing....why am I not getting anything?
The indexer analyzer took them out?   So then to find these documents, I
would want to either change the analyzer or take the quote out of the query?
Correct?
