Use tsvector for full text search, or allow custom filters

[emarchak]

Is your feature request related to a problem? Please describe.
We're looking to leverage tsvector for our full text search, but we really like Flop for all the param/filter handling that it can do.

Some discussion from the postgres documentation on why tsvector is awesome for full text search

Describe the solution you'd like
This library might not want to tie itself directly to postgres, so one potential option is to allow us to roll some custom filters in the API. I scanned the hexdocs, but it doesn't look like there's support for that at the moment.

Describe alternatives you've considered
We're very happy to contribute a PR to help unblock this issue, either for supporting tsvector or custom filters! Whatever supports the direction that Flop is looking to grow into.

Thanks for opening the issue. We have custom fields, which should allow you to model this: https://hexdocs.pm/flop/Flop.Schema.html#module-custom-fields

Thanks! We'll give that a try!
