-----------------------------------
Summary: Introduce 'limit' parameter in FacetStream.
Key: SOLR-12795
URL: https://issues.apache.org/jira/browse/SOLR-12795
Project: Solr
Issue Type: Sub-task
Security Level: Public (Default Security Level. Issues are Public)
Components: streaming expressions
Reporter: Amrit Sarkar
Let's look at an observation regarding "bucketSizeLimit" in facetStream; and
how we interpret it as a "limit". Suppose for 3 nested facets, bucketSizeLimit
= 10, we receive total 1000 rows. since bucketSizeLimit = limit; ONLY the first
top-level facet value's count will be returned; out of 10*10*10, 1*1*10th rows
will be fetched. And the behavior will be consistent for any bucketSizeLimit we
set,
How about we have a separate parameter "limit" other than "bucketSizeLimit"
which can be set to any arbitrary number (though should be <
bucketSizeLimit^no_of_nested_facets), and that limit can be said "500". In this
way, we will have the true SQL limit feature in place in FacetStream.
