Description

Hello

I am using prefetch to obtain most used data. When writing something more results are queried from server with remote option.

If prefetch data contains same items as the remote data, both of them are shown in the list (so they are duplicates).

I tried to Google it but only result is that "dupDetector" should be used like this dupDetector: function (remoteMatch, localMatch) { return remoteMatch.id === localMatch.id; }

But it seems that there is no dupDetector option available, is that correct? How should I do this?

Research direction
Investigate the typeahead.js source code to understand the data duplication mechanism when using remote and prefetch. Look for existing deduplication logic and consider implementing a 'dupDetector' option similar to the one mentioned in the documentation. Check the issue comments for any maintainer guidance on the desired API.
