Extend Rest Api with extended reporting possibilities

2

Via public api we can query reports and views.
However, they lack of the possibility to apply filters, search in specific fields or apply a full text search. Basically all the things we can do within a report on the portal

To achieve this, we currently have to use the undocumented internal api, that reports use when we apply filters and search for elements.

This works perfectly so far, but it would be much better to have this functionality also within the public api.
