But that was SS3.. Maybe run some tests before you go too far with it. See how quickly you can get an empty JSON response on a form field request handler.

Not the most secure thing, but it's blazing fast.

When I've done it in the past, i've actually just used a plain .php file, outside the framework, that does its own database connection, etc, and is able to create a response without all the overhead of the framework. (edited)

@JLeeuwis The problem you're going to run into with autosuggest is that it takes way too long to boot the controller to be useful. If you're not getting results within ~100ms, there's no point in having an auto suggestion.

  1. Field1: { eq: 'SomeValue' },
  2. Field2: { notIn: ['Value1', 'Value2' ]}
