Hi @brendan,
The matchmaking feature is added to your website with Match me for BuddyPress (https://wordpress.org/plugins/match-me-for-buddypress/). Match percentage is calculated based on number of matching BuddyPress extend profile fields and weightage of each field can be configured from admin.
For more about this plugin setup, please read the following documentation:
Unfortunately, I don’t see a way to query members based on the best match and to my knowledge, there is no plugin that you could install to add this feature to your website. We think that this feature requires custom development work.
For one, we recommend you try to reach MeshPros and request a customization quote:
These guys are the author of Match me for BuddyPress. So, they’ll be better informed and best suited to create this feature for you. Furthermore, they’ve quite a lot of experience with WordPress and BuddyPress development.
Best,
