Providing special characters in input when using QueryParser.

[Ankit Murarka <an...@rancoretech.com>]

Hello,
         I am using StandardAnalyzer for indexing all the documents.

While Searching say for Boolean/Wildcard/Prefix query, I am using 
*QueryParser* for the user supplied input.

But when I supply / as an input along with some characters like:

<param name="name" value="WSTFGH1028"/>\

I get a lexcial error due to presence of special characters in the code.

When I supply the same phrase in PhraseQuery, I get the required hit.. 
Understood that PhraseQuery and QueryParser handles query differently.

How can I achieve this. Accepting special characters also in user 
supplied inputs. I cannot make any changes in the indexing process . 
Also inputs like this will be very common from the user end..

Kindly guide.

TIA.

Ok..The problem seems to be solved.. Using the escape method of 
QueryParser, I am able to parse the given input with special characters 
also.

But if this leads to another pitfall someone may please guide..
