Faceting

[gwk <gi...@eyefi.nl>]

Hi,

I'm in the process of making a javascriptless web interface to Solr (the 
nice ajax-version will be built on top of it unobtrusively). Our 
database has a lot of fields and so I've grouped those with similar 
characteristics to make several different 'widgets' (like a numerical 
type which get a min-max selector or an enumerated type with checkboxes) 
but I've run into a slight problem with fields which contain a lot of terms.
One of those fields is country, what I'd like to do is display the top X 
countries, which is easily done with 
facet.field=country&f.country.facet.limit=X and display a more link 
which will redirect to a new page with all countries (and other query 
parameters in hidden fields) which posts back to the search page. All 
this is no problem, but once a person has selected some countries which 
are not in the top X (say 'Narnia' and 'Guilder') I want to list that 
country below the X top countries with a checked checkbox. Is there a 
good way to select the top X facets and include some terms you want to 
include as well something like 
facet.field=country&f.country.facet.limit=X&f.country.facet.includeterms=Narnia,Guilder 
or is there some other way to achieve this?

Regards,

Well, I had a bit of a facepalm moment when thinking about it a little 
more, I'll just show a "more countries [Y selected]" where Y is the 
number of countries selected which are not in the top X. If you want a 
nice concise interface you'll just have to enable javascript. With my 
earlier adventures in numerical range selection (solr-1240) I became 
wary of just adding facet.query parameters as Solr seemed to crash when 
adding a lot of facet.queries of the form facet.query=price:[* TO 
10]&facet.query:[10 TO 20] etc. etc

Thanks for your help,

Regards,

Gijs

You can use facet.query for each of the terms you want to include. You may
need to remove such terms from appearing in the facet.field=country results
in the client.

e.g.
facet.field=country&f.country.facet.limit=X&facet.query=country:Narnia&facet.query=country:Guilder
