[ckan-dev] Fwd: Faceting and Filtering in Recline Data Explorer

I've been sending most Recline stuff to okfn-labs atm but perhaps
should always be cross-posting.

Recline now has basic facets with filtering.

<http://okfnlabs.org/recline/demo/>

See the "Facets area" -- you can also add facets from the column menus.

More elaborate example (using this Newcastle city payments dataset on
the DataHub [1]):

Note that this illustrates several issues:

a) configuration of fields in DataStore Table for this dataset mean
that rather than faceting on whole field it is faceting on individual
terms. This is classic requirement to have a facet field separate from
original field (and creates Recline problem of how to handle that
association)

b) Filtering in ES does not affect facets as yet (will do very soon!)

c) UI is far from perfect (suggestions welcome).

Relevant tickets:

* Facet support: https://github.com/okfn/recline/issues/62
* Filter support: https://github.com/okfn/recline/issues/66
