Is your feature request related to a problem? Please describe.
No problems, just missing features that I will need to implement.

Describe the solution you'd like
A more comprehensive data filtering through the implementation of comparators.

The current alternative is to request all the data and compare on the front-end which is not network friendly.

I'm working on this currently. Should be done by the weeks end if not sooner. Going to thank @judilsteve for the help on some of the logic as well as cleaning up the logic in the function requestQueryHandler(), hopefully we should shave of some milliseconds in the response.

Data comparators are complete for the find endpoint. Update and remove endpoints to come soon.
