Hi Vincenzo, Are you saying that you used to see some numbers other than 0 and now you see 0? If it is always zero, it means that you are not using features that require uninverted version of field (mainly faceting) or that you have doc values enabled on all fields that are used in such scenario so there is no need to use fieldValueCache which is recommended.
FieldValueCache is defined by default so that’s why it is not defined in solr.xml, but you can override defaults.
