Instance Method Details

#add_advanced_search_to_solr(solr_parameters, req_params = params) ⇒ Object

this method should get added into the solr_search_params_logic list, in a position AFTER normal query handling (:add_query_to_solr), so it’ll overwrite that if and only if it’s an advanced search. adds a ‘q’ and ‘fq’s based on advanced search form input.

def add_advanced_search_to_solr(solr_parameters, req_params = params)
  # If we've got the hint that we're doing an 'advanced' search, then
  # map that to solr #q, over-riding whatever some other logic may have set, yeah.
  # the hint right now is :search_field request param is set to a magic
  # key. OR of :f_inclusive is set for advanced params, we need processing too.     
  if is_advanced_search? req_params
    # Set this as a controller instance variable, not sure if some views/helpers depend on it. Better to leave it as a local variable
    # if not, more investigation later.

      # ordinarily uses.
