Typically, they index the text in reverse order as well as forward order (similar to synonyms) so if you have a term in your field "reverse", you index "esrever" and now your leading-wildcard search for "*verse" becomes a trailing search for "esrev*".
There is an implementation in Solr, see: http://wiki.apache.org/solr/AnalyzersTokenizersTokenFilters#solr.ReversedWildcardFilterFactory that you might be able to get some ideas from.
