: > Optimizing cases where filters might be more expensive than the main query ;-)
: But you must have a real use case... that inspired this idea? Where : are apps/Solr "typically" using such expensive filters? i have no idea what usecase prompted yonik to start thinking about this, but the first example that came up in my mind is the semi-ubiquitous 'ACL' question that people always want to implement using a completley external authorization system. If you have no choice but to query an remote system to find out if a document should be included in a particular result set, odds are you don't want to pay the price of asking it only to find out afterwards that it doesn't matter anyway, because it doesn't metch a required query clause. -Hoss --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
