> ExpandComponent has an equivalent to the collapse qparser bug tracked in SOLR-15047...
> {quote}...has some very, _very_, old code/semantics in it that date back to when the {{FieldCache}} was incapable of differentiating between a document that contained '0' in the field being un-inverted, and a document that didn't have any value in that field.
> This limitation does not exist in DocValues (nor has it existed for a long time) but as the DocValues API has evolved, and as the [...] code has been updated to take advantage of the newer APIs that make it obvious when a document has no value in a field, the [...] code still explicitly equates "0" in a numeric field with the "null group"
