: To Erick's Point: Can you be more specific then 'certain circumstances'? : : Can anyone provide an example of when fieldValueCache would be used?
either FC and FVC are used "most of the time" -- which one is used depends on wether the field is multivalued or not, and if it's tokenized or not: ie: max 1 term per doc == FC, else FVC. The "most of the time" depends on facet.method... https://wiki.apache.org/solr/SimpleFacetParameters#facet.method ...if the "enum" method is used, them the filterCache is used.
