Hello,
With solr example, using facet.field=text creates UnInvertedField
for the text field in fieldValueCache. After that, I saw stats page
and I was surprised at counters in *filterCache* were up:
lookups : 213
hits : 106
hitratio : 0.49
inserts : 107
evictions : 0
size : 107
warmupTime : 0
. big terms (defined as matching more than 5% of the index) are
not uninverted since it's more efficient (both CPU and memory) to use
the filterCache and calculate intersections.
If so, when using both facet for multiValued field and facet for
single valued field/facet query, it is difficult
in fieldValueCache. After that, I saw stats page
and I was surprised at counters in *filterCache* were up:
Do they cause of big words in UnInvertedField?
Yes. big terms (defined as matching more than 5% of the index) are
not uninverted since it's more efficient (both CPU and memory) to use
the filterCache
