Want autocomplete to include interior words

Want autocomplete to include interior words

I'm quite new to jQuery and I'm using the autocomplete plugin on a test page.  Right now the autocomplete is suggesting titles where the typed word is only at the beginning, but I'd like it to also suggest titles where the typed word is inside.  For example, when I typed  applied I want to see suggestions for titles such as Journal of Applied Behavior Analysis in addition to Applied Biochemistry.
 
I've looked around on Google and a bit on these forums, and I believe the "matchContains" setting is what I have to adjust, but it seems that the behavior of the autocomplete doesn't change whether I use true, false, or "word" as the value.  Am I on the right track, or is there something else I need to adjust?
 
FWIW, the suggested titles (over 5000) are coming from a ColdFusion query.
 
Thanks for any help.
