All 3 languages? Is it based on the default_text_search_config ? When searching, we will generate SQL like this: OK, now here's where the documentation is sketchy. Next we create an index on the ts_vector column:ĬREATE INDEX node_ts_body on node USING gin(ts_body) įrom the documentation, it seems this index will know what config each row has. Presumably, this will generate tsvector data for every row, using what's in the regconfig column to determine the language. UPDATE node SET ts_body = to_tsvector(ts_config, body) We then generate the ts_vector column using this configuration: Provide a means to keep the ts_body column updated each time the underlying body data changes. We add 2 columns, ts_body and ts_config to contain the ts_vector data of body and the configuration (langugage) in theĪLTER TABLE node ADD column ts_body tsvector, ts_config regconfig Īt install time, the ts_config column will be populated so that it contains the language/config for each row. So, for example, we have a table called node with columns node_id, body Regconfig where each row will have a configuration name depending on the language of that row of data.
