Description

In OAK-8898, the "AlreadyClosedException" was fixed when reading facet results.

If the facets are read repeatedly (for each row), then the reader is now opened and closed each time. This can slow down the application.

It should be possible to cache the facet result in DelayedLuceneFacetProvider
