I have an array of managedobjects. Each has a title (name). I want to sort these NOT alphabetically, but by the one that matches a certain string the closest (the search query)
How would I do this?
Thanks

On google if you type red bean pie, red bean pie results come up (results ordered by string) – William Falcon Jan 16 '13 at 02:02

this is not close. this is exact. – vikingosegundo Jan 16 '13 at 02:07

In that example yes, but say I search for read bean pies make everyone hungry. At the top i would expect to see red bea pie if it is the closest match – William Falcon Jan 16 '13 at 02:17

so basically you want to teach the app to understand errors. Good luck — you just entered a minefield. If you want to have any chance of help, you should put some example of positive, negative and false positive hits to the question's text. – vikingosegundo Jan 16 '13 at 02:22

at least what you want to do is not simple. and core data wont be helpful at all. probably you will need a data structure in memory, that will keep the informations you want to search in memory so that you can do efficient searching on that. – vikingosegundo Jan 16 '13 at 02:32

It's probably best if you define your "closest" match function and simply assign closeness values to these objects (comparing to the search query) and sort by that instead.
