Configuration Solr fields

Search Fields

Targeting Search Queries at Configurable Fields

• Search queries can be targeted at configurable fields (or sets of fields) to return precise search results. Advanced search capabilities are provided through the Advanced Search Add-On Search fields in action

    # This one uses all the defaults set by the solr request handler. Which
    # solr request handler? The one set in config[:default_solr_parameters][:qt],
    # since we aren't specifying it otherwise. 
    
    config.add_search_field 'all_fields', :label => 'All Fields'

    # Now we see how to over-ride Solr request handler defaults, in this
    # case for a BL "search field", which is really a dismax aggregate
    # of Solr search fields. 
    
    config.add_search_field('title') do |field|
      # solr_parameters hash are sent to Solr as ordinary url query params. 
      field.solr_parameters = { :'spellcheck.dictionary' => 'title' }

      # :solr_local_parameters will be sent using Solr LocalParams
      # syntax, as eg {! qf=$title_qf }. This is neccesary to use
      # Solr parameter de-referencing like $title_qf.
      # See: http://wiki.apache.org/solr/LocalParams
      field.solr_local_parameters = { 
        :qf => '$title_qf',
        :pf => '$title_pf'
      }
    end

Sort Fields

    config.add_sort_field 'score desc, pub_date_sort desc, title_sort asc', :label => 'relevance'
    config.add_sort_field 'pub_date_sort desc, title_sort asc', :label => 'year'
    config.add_sort_field 'author_sort asc, title_sort asc', :label => 'author'
    config.add_sort_field 'title_sort asc, pub_date_sort desc', :label => 'title'
