How do I strip non alphanumeric characters from a string and keep spaces?
...
In this case I would use the bang method (gsub! instead of gsub) in order to clean the input permanently.
#permanently filter all non-alphanumeric characters, except _
@search_query.gsub!(/\W/,'')
This avoids a situation where @seach_query is used elsewhere in the code without cleaning it...
