You guessed my problem. Sorry; I don't feel too smart now. :)
One more question: Is there no way to combine FLAG_PARTIAL and FLAG_PHRASE?
In this same auto-complete, let's say I have two possible results:
The Difference Engine
A World of Difference
When I type in "difference engine" _not_ as a phrase, then I get both of
those in my results.
But if I do it as a phrase, it only seems to search whole words, so having
entered "difference en" in the field gives me no results, even if
FLAG_PARTIAL is turned on. Do these two flags not work together?
Thanks a lot,
Sean
