Thomas Mueller updated OAK-10549:
---------------------------------
Description:
Currently, reading many facets (eg. 20) at a time is quite slow when using a
Lucene index. We already cache the data, but performance is not all that great.
One of the reasons is that we run one Lucene query per facet column.
It is possible to speed this up, using eager facet caching.
