Subject Re: Defining tokenizer pattern with < character
Date Fri, 01 Mar 2013 17:30:30 GMT
Are you trying to strip out HTML tags? There are built-in classes that do that.

Or you might want to parse the XML or HTML before you pass it to Solr. An XML parser will
interpret CDATA so that you never have to think about it. The parsed data is just text.

you probably don't want to regex-escape the character class brackets "[" and "]", and you
should html-escape the angle brackets.
