Decide on facets from results
Hi,
If I don't have my facet list at query time, from the results can I select
some fields and by any means create a facet on them? ie after I get the
results I want to identify some fields as facets and send back facets for
them in the response.
A kind of very dynamic faceting based on the results!
Cld some one pls share their idea.
Thanks!
Anil.

Thanks for the suggestion Joe.
I will check on it.
Thanks!

Check out the new docs for the gatherNodes streaming expression. it Allows
you to aggregate and then use those aggregates as input for another
expression. You can even do this across collections.

On the same lines as Erik suggested but using facet stats instead. you can get stats on your facet fields in the first pass and then include the facets that you need in the second pass.

Re: Decide on facets from results

Maybe you could do this:
- MyFacetComponent extends FacetComponent
- MyFacetComponent.process(): The results will be available at this
point; look at them and decide which facets to fetch and return

Re: Decide on facets from results

What about a custom component? Something similar to spell-checker? Add
it last after everything else.
It would have to be custom because you have some domain magic about
how to decide what fields to facet on.

Alex.

Mark:
You can do anything you want that Java can do ;). Smart-alec comments
aside, there's
no mechanism for doing this in Solr that I know of. The first thing
I'd do is try the two-query-
from-the-client approach to see if it was "fast enough".

Re: Decide on facets from results
Posted by Mark Robinson <ma...@gmail.com>.
Thanks Eric!
So that will mean another call will be definitely required to SOLR with the
facets, before the results can be send back (with the facet fields being
derived traversing through the response).
I was basically checking on whether in the "process" method (I believe
results will be accessed in the process method), we can dynamically
generate facets after traversing through the results and identifying the
fields for faceting, using some aggregation function or so, without having
to make another call using facet=on&facet.field=<field_name>, before the
response is send back to the user.
Cheers!

Results will vary based on how you indexed those fields, but sure… &facet=on&facet.field=<field_name> - with sufficient RAM, lots of fun to be had!
