IMDB search engine is a near-perfect engine for titles, indeed it works very well. They probably worked hard to make that.
It cannot (time, capabilities and what our server allows to do) do as good as they did, but I can add a feature to have "similar" matches (instead of current "exact" matches).
I already made few tests, I just have to find time to integrate that in the site.
Downsides are:
- made for English terms, so results will not be so good for non-English titles
- skips short words (less than 4 letters I think)
So I have to combine it with current system, not just replace it.
