Google adds synonym searches
Google has introduced synonym searching as part of its advanced search features. If you are looking for a word and all words like it, just add the "~" character before the word you are wanting to search. Example: ~help (Google should then search for words such as "assistance", "guidance", and "aid" in addition to "help"). For more information on advanced Google searches, see Google's help page:
