Prefixes quick search results not as expected

[avdn2011]

Hi folks. While learning and playing around with a NetBox Docker (v3.0.11) I was very happy with the quick search possibilities of NetBox. We have a lot of prefixes and quick search is a very convenient way of quickly finding the prefixes you need.

Now we have installed NetBox v3.1.6 for production use (no Docker this time). When using the quick search function in the Prefixes screen the results seem quite random. In our Docker NetBox, when quick searching for i.e. '168' the results are as expected: all '192.168' prefixes are shown as well as something like '10.54.168.0'.
When doing the same on the new NetBox (containing the same data set as the Docker NetBox) only 2 results are shown (while a page search in the browser counts 159 results). These 2 results both have '168' somewhere in the Description field.

This behavior is not only on our NetBox but can also be reproduced on https://demo.netbox.dev/ipam/prefixes/

It looks like quick search for prefixes is only looking in the Description field and ignoring the Prefix field. Something similar happens when quick searching IP Addresses. Is this a bug? Or has there been a change in quick search functionality?
