Add more predicates for filters

[antho1404]

https://github.com/mesg-foundation/engine/pull/1738 added a few predicates for filters but we could add even more.

One that I feel is really missing would be the

• NEQ (not equal)
• MATCH (match a regex)

Here is a list of predicates that could be implemented too https://github.com/activerecord-hackery/ransack#search-matchers
