Module: Blacklight::SearchFields

Extended by:
Deprecation
Defined in:
app/controllers/concerns/blacklight/search_fields.rb

Overview

Module to deal with accessing (and setting some defaults) in an array of hashes that describe Blacklight search fields. Requires the base class this module is added to implements a #blacklight_config method that returns a hash, where blacklight_config will be an array of hashes describing search fields.

Search Field blacklight_configuration Hash =

:key

“title”, required, unique key used in search URLs to specify search_field

:label

“Title”, # user-displayable label, optional, if not supplied :key.titlecase will be used

:qt

“search”, # Solr qt param, request handler, usually can be left blank; defaults to nil if not explicitly specified

:solr_parameters

{ :qf => “something” } # optional hash of additional parameters to pass to solr for searches on this field.

:solr_local_parameters

{ :qf => “$something” } # optional hash of additional parameters that will be passed using Solr LocalParams syntax, that can use dollar sign to reference other solr variables.

:include_in_simple_select

false. Defaults to true, but you can set to false to have a search field defined for deep-links or BL extensions, but not actually included in the HTML select for simple search choice.

Optionally you can supply a :key, which is what Blacklight will use to identify this search field in HTTP query params. If no :key is supplied, one will be computed from the :label. If that will result in a collision of keys, you should supply one explicitly.
