[External Email]

Hi Eliot,

index:facets is a good pointer: It collects statistical information on
all distinct path and values of the database. The number of distinct
stored values is limited, but it can be increased with the MAXCATS
option [1].

The current BaseX value indexes don’t store any location/path
metadata, only the values themselves, so you’ll indeed need to collect
the values with XPath, as you already did.

Best,
Christian
