#add_spatial_params(solr_params) ⇒ Blacklight::Solr::Request

Adds spatial parameters to a Solr query if :bbox is present. :bbox should be passed in using Solr lat-lon rectangle format e.g. “minX minY maxX maxY”

Parameters:

  • solr_params (Blacklight::Solr::Request) —

    :bbox should be in Solr

Returns:

  • (Blacklight::Solr::Request)
