Query performance

Hi all,

                Does the following query has any performance impact over
the second query?

 

+title:lucene +(title:lucene -name:sid)

 

 

+(title:lucene -name:sid)

the second should in theory be faster then the first just because of 
reduced number of comparisons needed -- but wether or not you would 
actually notice a difference is mainly going to depend on your data.
