Trigger instant search only after x characters entered?

In order to limit the number of operations, is there a way to only trigger the instant search after x amount of characters entered in the field (e.g. 3?)

Seems like it was referenced here:

but not sure if anything was ever implemented

Hi @jessica_wong ,

Using InstantSearch.js, this can be done using the searchFunction. This function act as a hook with which you can decide wether or not you want InstantSearch.js to actually proceed with the search.

We just released the beta of the v2, which actually improves the usability of the searchFunction.

On the UX side, I must warn you that this can lead to mixed feelings from your users as they use backspace to go back from 3 to 2 characters, no update then.
