Arguments

model

Active Record model configured for multisearch.

time_source

end

Instance Method Details

#rebuild ⇒ Object

Populates search documents without first clearing existing documents. Uses the model's rebuild_pg_search_documents override when available; otherwise updates records individually for conditions, dynamic content, or additional attributes, and bulk-inserts for plain column content.
