问题
I am trying to perform a solr query with multiple query fields including a not equals operator.
Example query:
field1:abc OR -field2:def
The problem is the query returns results for an AND operation instead of an OR, as if the query was:
field1:abc AND -field2.def
Both queries always return the same result. What is the correct syntax to achieve a correct OR result?
I am currently using solr 3.5.
Thanks

Maybe try the following:
field1:abc OR (*:* -field2:def)
回答2:
for field1:abc OR -field2:def this also works
-(-field1:abc AND field2:def) .
