Hi Erik: When using [e]dismax, does configuring q.alt=*:* and not specifying q affect the performance/caching in any way?
As a side note, a while back I configured q.alt=*:*, and the application (via SolrJ) still set q=*:* if no user input was provided (faceting). With both of them set that way, I got zero results. (Solr 3.4.0) Interesting. Thanks, Jeff On Nov 22, 2011, at 7:06 AM, Erik Hatcher wrote: > If all you're doing is filtering (browsing by facets perhaps), it's perfectly > fine to have q=*:*.
