Highlighter and href fields

Is there anyway I stop highlighting text if it is a href/url
etc...? The problem occurs when the field content is a URL
which contains the query e.g. my search is for .net and
fields has value http://jkjsd.net. After
applying highlighter, it becomes http://jkjsd<b
>.net</b>, which is a wrong URL. Can I filter
it out?
