Dynamic Faceting with Bobo

[Sudarshan Kadambi]

Hi,

I'd like to know if Bobo supports Dynamic Facets. I'm using Solr
currently and you tell Solr what facets you want it to produce. I've
over 70 possible facets - not all of them will be relevant to the
result set (on average, about 5-10 out of the 70 facets will be
relevant). I'd like it if the facets were identified for me rather
than me asking for all facets and trimming out those with no counts.

Hi Sudarshan:

    Yes, bobo supports this. You would implement a RuntimeFacetHandler. I can walk you thru the details if you provide some more context or info.

Thanks John.

Sure, here's some more details about my requirements:
I've about 500K documents in my index. My index is not updated in real-time - it gets refreshed twice a day. I've about 70 facets - these will likely grow to a 100 over time. The number of possible values in the facets vary from 2 (Gender facet) to 2K (Industry facet). 

I'm completely new to Bobo. I'd like to understand what is it about Bobo's design that allows it to provide dynamic faceting. I'd also like to understand the performance implications of this feature. Meanwhile I'll look through the Bobo docs/source to see what a RuntimeFacetHandler does.
