Remote data search with UISearchBar

[djp_phillips]

I need to get remote data when I search a TableView using the SearchBar.

What are the best practices for this?

My concern is that if I send a new HTTP request each time the user changes the search bar's value, I could end up blocking the application because too many HTTP requests are being made, but also if I have many requests, it's also possible for an older request to lag and arrive after a newer request, so the results won't be very stable.

How would you perform remote data requests from a search bar effectively ?

Thanks

there is no options, if your "remote data" can't be downloaded (and cached) on a BIG file (sqlite or in parsed xml in ram), you need to do many http request, maybe with a lag of 0.5/1.0 second (so if the user tap many characters will start only when finished to write).
