Hi guys,
It has been a while I was thinking about this and yesterday I took a look
into the code :
I was wondering if the termEnum approach is still a valid alternative to
docValues when we have low cardinality fields.
The reason I am asking this is because yesterday I run into this piece of
code :
org/apache/solr/request/SimpleFacets.java:448
if (method == FacetMethod.ENUM && sf.hasDocValues()) {
// only fc can handle docvalues types
method = FacetMethod.FC;
}
So it seems that , if you enable the docValues in the schema, we are always
going to use them even if the method select is term enum.
So does it mean, in case we have enough disk space, that it is always
suggested to use docValues now ?
Of course I know that would be great to move as soon as possible to the new
json facet API approach.
P.S. still verifying the famous legacy facet degradation on latest Solr
compared to old Solr4.
Cheers
