Houston Putman resolved SOLR-11437.
-----------------------------------
Resolution: Duplicate
Note that double and float fields do not use NormsFieldExistsQueries or
DocValuesFieldExistsQuery for {{[* TO *]}} queries. This is because those query
implementations will match documents with {{NaN}} values, and [* TO *] should
not match {{NaN}} values.
> double open ended range queries should be optimized to
> DocValuesFieldExistsQuery or NormsFieldExistsQuery

> Key: SOLR-11437
> URL: https://issues.apache.org/jira/browse/SOLR-11437
> Project: Solr
> Issue Type: Bug
> Reporter: Chris M. Hostetter
> Priority: Major
>
> DocValuesFieldExistsQuery & NormsFieldExistsQuery are efficient ways to
> determine if a doc has a value in a given field (assuming the field has
> docValues or norms respectively)
> Since Solr's schema knows if/when these properties are true for a given
> field, we should be able to optimize some of the {{field:[* TO *]}} usecases
> to use these queries under the covers -- notably in
> {{FieldType.getRangeQuery}} and subclasses that override it, but there may be
> other cases where they could come in handy as well
