Do > you think this is possible? Autosuggestion functionality will need tuning, just like search results. In fact, autosuggestion is really a specialized form of search application. It could be implemented with a separate index or separate fields. Say that we only wanted to offer suggestions derived from the `title` field. Split each title into an array of words. Then for each word, index starting at some letter, say the third. For the title `hello world`, you'd get the following tokens: hello -> hel hell hello world -> wor worl world Then at search time, perform a search query with every keystroke. h -> (no result) he -> (no result) hel -> "hello world" Once you've got basic functionality running, experiment with minimum token length, adding Soundex/Metaphone, performing character normalization, etc. Marvin Humphrey
