Search documents with blank content

[vanboom]

It is possible for the user to reference an attribute or attributes for multisearchable that contains no data. If there is no data for the content of the pg_search_document, a record is created anyway.

Suggestion - it may be more efficient to not create a pg_search_document record when there is no searchable data to be stored.

A work around exists using the if feature...

  multisearchable :against=>[:serial_number, :model_number], if: :has_multisearchable?

  def has_multisearchable?
      serial_number.present? or model_number.present?
  end
