text: are there any search engines that search for synonoms? i'm working on a worksheet in which i have to find quotes.  most, such as "man cannot learn without god's help" only turn up the original worksheet and no actual results.  do any search engines exist that will automatically search (without me typing in various ways) for various forms, such as "one can't learn without god's help" or "man cannot learn without help from god"? on google, if you want to search not only for your search term but also for its synonyms, place the tilde sign ("~") immediately in front of your search term.
