field:* vs field:[* TO *]

[Hendrik Haddorp <he...@gmx.net>]

Hi,

I had already asked this on the Solr mailing list but would like to 
confirm this here:

If I want to query all documents that have a field or do not have a 
field does it really perform better to use "field:[* TO *]" instead of 
"field:*" ? I would have expected that Lucene handles both queries 
internally the same and is not really expanding the wildcard to all 
possible tokens.

regards,
Hendrik

This is going to depend on the queryparser that you are using and the field
type of `field`. I agree both should be handled as efficiently.
