Hoss Man commented on SOLR-792: ------------------------------- i'm with grant ... i had an IRC conversation with erik a while back where i pointed out that there isn't anything intrinsicly "tree" oriented about this patch -- it can be used in cases where you've got multiple fields expressing a tree structure, but it can also be useful for fields that are totally orthogincal to eachother (ie: the "cat" and "inStock" example) What this is essentially doing is treating each field as a vector containing the constraint counts for that field, and taking a "cross product" to produce an N-dimensional matrix showing the counts for each permutation. Which led to my suggestion for "matrix faceting" or "cross product faceting" The other way to look at it is that it's "Decision Tree Faceting" in that it tells you "for facet A, the constraints/counts are X/N, Y/M, etc.... if you were to constrain A by X, then the constraint counts for B would be S/P, T/Q, etc... ie: it tells you in advance what the "next" set of facet results would be for a field if you apply a constraint from the current facet results. but calling it just "Tree Faceting" seems missleading to me. that seems more applicable to something like SOLR-64 > Tree Faceting Component > ----------------------- > > Key: SOLR-792 > URL: https://issues.apache.org/jira/browse/SOLR-792 > Project: Solr > Issue Type: New Feature > Reporter: Erik Hatcher > Assignee: Erik Hatcher > Priority: Minor > Attachments: SOLR-792.patch, SOLR-792.patch, SOLR-792.patch, > SOLR-792.patch, SOLR-792.patch, SOLR-792.patch > > > A component to do multi-level faceting. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
