API Query operators on text fields: starts_with and ends_with

[qroac]

I am working on some filter functions for huge data tables in our frontend.
For some of the intended functions, I need filter operations that I cannot find in the documentation:

starts_with and ends_with to search for records that have the queried field starting or ending with a required value

Is this already possible and just not listed in docs?
Or is this already planned for future releases?
