Hoss Man created SOLR-6927:
------------------------------
Summary: optimze various usages of DocTermOrdsRangeFilter and
DocValuesRangeFilter to useFieldValueFilter if appropriate
Key: SOLR-6927
URL: https://issues.apache.org/jira/browse/SOLR-6927
Project: Solr
Issue Type: Improvement
Reporter: Hoss Man
there are handful of code paths in solr that use DocTermOrdsRangeFilter and
DocValuesRangeFilter to do range queries over fields with DocValues -- and in
many cases this is to account for the "field:[* TO *]" type usecase (in some
cases it's even done internally as an optimization of the "field:*" usecase.
in these DocValue situations, if we know that hte uper & lower bounds are both
null, we should make this code more optimized to use FieldValueFilter instead
