Delete documents with empty fields

[Massimo Schiavon <ms...@volunia.com>]

I want to delete all documents with empty title field.
If i run the query -title:[* TO *] I obtain the correct list of 
documents but when I submit to solr the delete command:

curl http://localhost:8080/solr/web/update\?commit=true -H 
'Content-Type: text/xml' --data-binary \
'<delete><query>-title:[* TO *]</query></delete>'

none of the documents were deleted.

After a bit of debugging I have noted that the query was internally 
rewritten by org.apache.lucene.search.Searcher.createNormalizedWeight to 
an empty query.

It is a bug or there is another way to do this operation? (or there is 
no way?)


Regards

Not sure but '<delete><query>+*:* -title:[* TO *]</query></delete>' may do the trick.
