-------------------------------------
Summary: Speed up tag/exclude faceting
Key: SOLR-15413
URL: https://issues.apache.org/jira/browse/SOLR-15413
Project: Solr
Issue Type: Improvement
Security Level: Public (Default Security Level. Issues are Public)
Reporter: Joel Bernstein
One of the major features Solr offers for e-commerce search is tag/exclude
faceting. This feature currently requires that the main query be executed
twice: Once for the matching/scoring phase and again for computing a DocSet
that matches tag/exclude filters. Executing the main query twice is fine as
long as the main query is fast. But if the main query is heavy, executing it
twice can be a performance bottleneck.
This ticket will propose and hopefully implement a design that allows the main
query to be run once when tag/exclude faceting is used.
