Subject [jira] Updated: (SOLR-1240) Numerical Range faceting
Date Sat, 10 Jul 2010 01:06:52 GMT


Hoss Man updated SOLR-1240:

    Attachment: SOLR-1240.patch

Updated version of Gijs previous patch that applies cleanly to trunk

Misc comments on the patch...

* i agree with erik, we should split up SimpleFacets and FacetComponent, but that's a seperate
probelm.  if the patch works well, let's commit and then refactor -- besides: there is enough
similarity with date faceting that they should stay together and share code anyway, so let's
just put number faceting with date faceting now and move them together later when we split
up facet.query, facet.field and
** I think in an ideal world: we could eliminate and facet.number and just let
people use "facet.range=fieldName" along with legitimate values for the other facet.range.*
params and have it do the right thing depending on the type of fieldName ... but it might
take a little while to get there
* Note: current patch breaks distributed test, but i think that's just a foolish assumption
on the part of the test.
* functionality currently breaks if any of the numeric params is a float value -- the code
does lots of special testing to see if the _field_ is a "float" field or not, but it still
tries to parse every param as both a long and a float -- we need to fix that so any number
is valid (even if the field type is "long" it's totally reasonable for people to ask for a
gap of "0.5")
* the param was added after this patch was contributed, this patch uses
it's own param/model for dealing with inclusion/exclusion -- it should be changed to match
the conventions dates uses

> For faceting numerical ranges using many facet.query query arguments leads to unmanageably
large queries as the fields you facet over increase. Adding the same faceting parameter for
numbers which already exists for dates should fix this.
