[Enhancement] Autocompletion by similarity

[SunboX]

Could you implement a option to get autocompletion by similarity? Like this:

http://phpjs.org/functions/levenshtein:463

Would be really cool! Maybe a combination from current algorithm (first chars matching) and the levenshtein algorithm is also possible.

One more: approximated string matching

Thats very interesting. Maybe a demo showing how to do it would be cool, not something builtin. I'll try it out. Thanks!

I'm interested on your application, can you explain it?

[SunboX]

Yes, i´m looking for an autocompletion, that suggests the following:

I´m typing: Mac Donalds Suggests:

McDonald´s Mac Doctors Mac Fastfood

A normal autocompletion would only show the last two suggests. But that´s wrong in this case. The order of the suggested words should be the levenshtein index for similarity. Lower index on top.

[SunboX]

In my case the autocompletion list would be prefilled with location names around a persons location. And if that person types the name of a location, it should try to get the name the person is looking for.

This is what i want to get (not tested yet!):

Is it possible to modify filter behavior, that they return integers instead of booleans? Like this:

So we could sort the filtered items by best fitting. ;o)

[fabiomcosta]

cool stuff, im thinking about this to make it in a way that can be very generic, that you could define any kind of sorting on your options...

[fabiomcosta]

Hey man you can use the similarity functionality without needing to change anything... look at this and tell what you think: http://jsfiddle.net/7cUgF/1/ I've reduced a little the levenshtein function.
