Update parsers documentation

**Feature request**
It would be great to have pagination for core.

**Use case**
Many users need this functionality for production deployments.

**Implementation idea**
Add a new config option `enable_pagination` with default `false`.

Start by locating the parsers and core entry points, then inspect how configuration options are defined and tested. Clarify the intended pagination behavior and scope before making changes. Done means core supports pagination behind enable_pagination, whose default is false, with corresponding documentation and tests.
