Custom ordering of results

[Jonah Greenthal]

I'd like to reorder my search results (on the client side) to prioritize ones that start with the search text, while still displaying ones that don't. How can I do that?

(This seems related, but not identical, to https://groups.google.com/forum/#!searchin/select2/sorting/select2/oPZMI6lbSzM/W1uDZR_JnpwJ and https://github.com/select2/select2/issues/3106.)

Thanks!

Anyone? Please?

Sorry about the delay, I can only answer half of your question.

Select2 provides the `sorter` option (previously called `sortResults`) which takes in the array of results to be displayed and expects a sorted array to be returned as a result. Select2, by default, does not do any special sorting and just passes the original array of results through. You can override the `sorter` method (it's a function) when you initialize Select2.

You can find an example in the old documentation (change `sortResults` to `sorter`): http://select2.github.io/select2/#sort_results

Also note that only the first parameter (`results`) is supported in Select2 4.0.0.

The two links you provided were about ordering the selection, not the results.

Thanks! Is there documentation on the object types for the arguments?

[Jonah Greenthal]

Okay, I think I figured that out -- but how do I access the query,
given that only the results parameter is supported in v4?

Thanks,
Jonah

Because Select2 4.0.0 separates the retrieval of results from the display of them, the `sorter` method can't provide the context for the query (and as a result, the search term). You can intercept this in other areas and store it in a global variable though.

You can find an example here on this Stack Overflow answer for underlining term matches in search results: http://stackoverflow.com/q/28958620/359284

Basically you need to override `language.searching` (which takes in `query`) such that it stores the argument to a global variable and returns the "Searching..." text you would normally expect. You can guarantee that the searching translation will be called before the results are sorted and rendered.
