[jira] [Updated] (SOLR-7296) Reconcile faceting implementations
[ https://issues.apache.org/jira/browse/SOLR-7296?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
David Smiley updated SOLR-7296:
-------------------------------
Summary: Reconcile faceting implementations (was: Reconcile facetting implementations)
I fixed the typo in the title; it was taking me _forever_ to find this issue -- even with http://jirasearch.mikemccandless.com/
I took a deeper look at the new Facet Module (ported from Heliosearch) and I like it a whole lot! I wish I had done the heatmap faceting stuff there; it would have saved me some grief. I have more advanced heatmap analytics planned and I will do it in the Facet module not just because I like the API better but because I'll need to leverage the analytics there. It mainly needs internal javadocs. It's important to note that it's both a _framework_ for doing faceting, and it has some implementations of the various types that plug into that framework. By comparison, FacetComponent & SimpleFacets has no real framework and isn't something we should substantially improve going forward, IMO. In principle, I don't see why Lucene's facet module couldn't be used here as well as an implementation (ala facet.method=?), plugging into Solr's new Facet module. I'm not saying it's trivial but my point is that this shouldn't be an either-or; it's complementary. Let the Facet Module be the framework, have implementations plug-in, and put the JSON parse & standard/classic request param parsing a layer above.
I haven't looked at the Analytics Contrib module but it's lack of distributed support is likely a non-starter, and it's not clear what capabilities lie there that aren't in the new Facet Module.

> SOLR-7214 introduced a new way of controlling faceting, the unmbrella SOLR-6348 brings a lot of improvements in facet functionality, namely around pivots. Both make a lot of sense from a user perspective, but currently have completely different implementations. With the analytics components, this makes 3 implementation of the same logic, which is bound to behave differently as time goes by. We should reconcile all implementations to ease maintenance and offer consistent behaviour no matter how parameters are passed to the API.
