Do not confuse this class with Search::Tools::RegExp::Keywords.

Search::Tools::Keywords extracts the meaningful words from a search query. Since many search engines support a syntax that includes special characters, boolean words, stopwords, and fields, search queries can become complicated. In order to separate the wheat from the chafe, the supporting words and symbols are removed and just the actual search terms (keywords) are returned.

This class is used internally by Search::Tools::RegExp. You probably don't need to use it directly. But if you do, read on.
