I'm observing the following behavior with Solr 9.7.0: Searching for attributes that are empty (have no value), I'm using the syntax "-attributename1:*". This query works correctly and returns many results (because attributename1 is empty for many documents):
http://hostname:8983/solr/solr1/select?q=-attributename1:*%20AND%20Class:Document&wt=xml&rows=10000 Whereas this query looking for either attributename1 OR attributename2 being empty returns zero results: http://hostname:8983/solr/solr1/select?q=-attributename1:*%20OR%20-attributename2:*%20AND%20Class:Document&wt=xml&rows=10000 enclosing the first 2 attributes in parentheses doesn't change the behavior, still zero results. http://hostname:8983/solr/solr1/select?q=(-attributename1:*%20OR%20-attributename2:*)%20AND%20Class:Document&wt=xml&rows=10000 Does anyone know why this is happening? It should be still returning the results of attributename1 being empty. Henry Farmerie Siemens Product Lifecycle Management Software Inc.
