Re: getting error when ":" in the query

[Ranveer Kumar <ra...@gmail.com>]

Hi
thanks for reply.

Is it possible to filter the special character. If I will allow then need to
put "\" before every special character, which will consume time and create
performance issue. So I want to just filter those special char from user
input query.

However I would also like to know that, is there any short way to put "\"
before special character which will not effect the performance.

thanks
with regards

There is a static method in org.apache.lucene.queryParser.QueryParser that does this: QueryParser.escape(String s);
