53.59. pg_ts_config #

pg_ts_config 目录包含表示文本搜索配置的条目。配置指定特定的文本搜索解析器和字典列表，用于每个解析器的输出标记类型。解析器显示在 pg_ts_config 条目中，但标记到字典的映射由 pg_ts_config_map 中的附属条目定义。

The pg_ts_config catalog contains entries representing text search configurations. A configuration specifies a particular text search parser and a list of dictionaries to use for each of the parser’s output token types. The parser is shown in the pg_ts_config entry, but the token-to-dictionary mapping is defined by subsidiary entries in pg_ts_config_map.

PostgreSQL 的文本搜索功能在 Chapter 12 中有详细的描述。

PostgreSQL’s text search features are described at length in Chapter 12.
