Use "appends" instead of "defaults".

Dynamic facets during runtime

[Jeyaprakash Singarayar]

Hi,

Our application has a facet select admin screen UI that would allow the
users to add/update/delete the facets that has to be returned from Solr.

Right now we have the facet fields defined in the defaults of
requestHandler.

So if a user wanted a new facet, I know sending that newly selected facet
with the query would override the list in the solrconfig.xml

If there any better way rather than making all the facets sent through
querytime.

Thanks,
Jeyaprakash

Dynamic Facets

[Way Cool]

Hi, guys,

We have more than 1000 attributes scattered around 700K docs. Each doc might
have about 50 attributes. I would like Solr to return up to 20 facets for
every searches, and each search can return facets dynamically depending on
the matched docs. Anyone done that before? That'll be awesome if the facets
returned will be changed after we drill down facets.

I have looked at the following docs:
http://wiki.apache.org/solr/SimpleFacetParameters
http://www.lucidimagination.com/devzone/technical-articles/faceted-search-solr

Wondering what's the best way to accomplish that. Any advice?

Thanks,

YH

YH -

One technique (that the Smithsonian employs, I believe) is a technique to index 
the field names for the attributes into a separate field, facet on that first, 
and then facet on the fields you'd like from that response in a second request 
to Solr.

There's a basic hack here so the indexing client doesn't need to add the 
fields used field: https://issues.apache.org/jira/browse/SOLR-1280

Ideally, this could all be made part of one request to Solr - and I can 
envision a pre-faceting component (post querying) to dynamically figure out the 
best fields to facet on, set those into the request context, and the rest is 
magic.

Re: Dynamic Facets

[darren]

You can issue a new facet search as you drill down from your UI.
You have to specify the fields you want to facet on and they can be
dynamic.

Take a look at recent threads here on taxonomy faceting for help.
Also, look here[1]

Re: Dynamic Facets

[Way Cool]

Thanks Erik and Darren.
A pre-faceting component (post querying) will be ideal as though maybe a
little performance penalty there. :-) I will try to implement one if no one
has done so.

Darren, I did look at the taxonomy faceting thread. My main concern is that
I want to have dynamic facets to be returned because I don't know what
facets I can specify as a part of query ahead of time, and there are too
many search terms. ;-)

Thanks for help.

Dynamic facets?

[Darren Govoni]

Hi,
  I was wondering if there is a way to retrieve the facets from a query
based on their mincount without specifying facet.field? 

I submit a query and want to retrieve all the faceted fields with
mincounts  2, but don't know what they might be since I also use
dynamic fields. Is this possible?

thanks,
Darren

No, one must specify the field name on which one wants to facet. It seems
that you don't care about the field names, just the individual term and
count. If so, you can create a copy field for all the dynamic fields you
have.

SMILE/Rails/Babel and Dynamic Facets?

Erik:

You are doing some pretty cool stuff with flare! I am amazed! Now I have some 
questions :-)

- Smile and Babel does everything and its so easy so I wonder why you need 
ruby/rails for flare? What I mean is that one could get XML feed directly from 
Solr to smile if the xml is formatted correctly correct? no? I am guessing you 
have bigger plans :-) .. I am just curious

- A different question regarding dynamic facets, I wonder if its possible to do 
facets based on term frequency? I mean what one need to do lets say you 
decide that show automatically the top 10 medium_facets or top 10 
genra_facets.. or just the top 10 term frequency facet .. and then show where 
this sub facets.. For lack of better term I am using the word dynamic facets as 
the index will change.. how will one go about doing that? I hope I am able to 
explain correctly..

Oh sure, you could totally map Solr directly into SIMILE Exhibit, via  
JSON.  However, the Flare Rails application does maintain state so  
the current query and filter state are taken into consideration for  
the data sent to Exhibit.  It was really just a glorious hack to tie  
the two together that easily.  More is needed. Flare has a few hard- 
coded spots that need to be factored out into configuration, and also  
the Exhibit controller only sends out a maximum of 10 items at the  
moment.  So its a proof-of-concept, and whether its a keeper in Flare  
remains to be seen.   I would like to see SIMILE Timeline support get  
added eventually too and see how that fits.

I'm sure this could be done.   Flare can evolve into a UI that  
adjusts based on the state of the index, for sure.  I haven't  
contemplated this far yet, but I think you're on the right track.
