In solr i have a multiValued field called animal and it has the values {cat,dog} is it possible to get the number of values inside the multiValued field in solr(in my example 2)?
If you want to count the items in a multivalued field use CountFieldValuesUpdateProcessorFactory
There is no direct way to get the count of items in a multivalued field.
You can always maintain the field count during indexing and use it.
If not using during query time, you can always count the list size.
