Hey, these are two separate problems in fact. Let me try to explain.
Throwing a query like "title: foo bar" straight into Ferret, when that gets turned into FQL, it becomes basically "look for 'foo bar' in the 'title' field", as you figured. Quoting the whole lot will throw the query towards the index, and the default_field value will be used to decide which fields should be queried for "title: foo bar". Since it defaults to "*", it'll query all fields in every document. Now the reason why a query like "Title: foo bar" won't match any results with "title" in it is, simply put, the analyzer you're using. If you're using the StandardAnalyzer (if you didn't specify otherwise, then that's what you're using), the behavior you can expect is it will catch whole words, separated by spaces, minus stop words (or, and, by, etc...). So "titl" will never match "title". If you're looking for something that gives you half-string matches, I'd go for a RegexpAnalyzer and use a regex like "*", which would turn every character into a token. This is a bit nightmarish because you'll get an insane number of matches for everything, but right now I can't think of a better way (maybe declare a mininum number of chars for a query and filter out results with very low score?). Or if you're looking for stemming (query for "titles", "titling" returning results with "title"), have a look at http://rubyforge.org/pipermail/ferret-talk/2007-March/002782.html Hope that helps.
