InfoClick is designed to be used with Apple's Mail application to navigate through your emails to see the words, contacts, and information within. InfoClick knows precisely what words you've used, so there's no guessing; it offers a guided process of progressively narrowing down the matches in a series of simple choices. That means you can't ever produce a search with zero matches. For example, when you're searching for all emails containing a particular word, InfoClick would show the completions "connection", "connexion", and (the misspelled) "connecsion", if you'd actually used those words in your emails.
