  Each record can include any data self::get_document might need but it must:
  - Include an 'id' field: Unique identifier (in this area's scope) of a document to index in the search engine
  If the indexed content field can contain embedded files, the 'id' value should match the filearea itemid.
  - Only return data modified since $modifiedfrom, including $modifiedform to prevent
  some records from not being indexed (e.g. your-timemodified-fieldname >= $modifiedfrom)
  - Order the returned data by time modified in ascending order, as \core_search::manager will need to store the modified time
  of the last indexed document.
  
  Since Moodle 3.4, subclasses should instead implement get_document_recordset, which has
  an additional context parameter. This function continues to work for implementations which
  haven't been updated, or where the context parameter is not required.
