Li Fanxi commented on SOLR-792:
-------------------------------
I have a question about facet.pivot.mincount. Does this parameter defined as
the limitation for "minimum number of documents" that should be included in the
result?
In the current implementation, I found that this parameter also takes effect
for the number of facets fields, caused by the following code in doPivots
function:
{code}
NamedList<Integer> nl = sf.getTermCounts(subField);
if (nl.size() >= minMatch ) {
pivot.add( "pivot", doPivots( nl, subField, nextField, fnames, rb,
subset, minMatch ) );
values.add( pivot ); // only add response if there are some counts
}
{code}
I don't understand why we need to compare minMatch to nl.size().
With this code, if we do pivot faceting on the fields "cat,manu_id_s", when
cat='electronics' and we have 50 documents distributed in 3 different
"manu_id_s". If we limit the result with facet.pivot.mincount=5, no result will
be returned, because there are only 3 different "manu_id_s". Is this the
desired behavior for the "facet.pivot.mincount" parameter?
