CREATE TEXT SEARCH DICTIONARY
CREATE TEXT SEARCH DICTIONARY — 定义新的文本搜索词典
CREATE TEXT SEARCH DICTIONARY — define a new text search dictionary
Description
CREATE TEXT SEARCH DICTIONARY 创建新的文本搜索词典。文本搜索词典指定用于识别搜索时相关或不相关的单词的方法。词典依赖于文本搜索模板，它指定实际执行工作的函数。通常词典会提供一些选项，用于控制模板函数的详细行为。
CREATE TEXT SEARCH DICTIONARY creates a new text search dictionary. A text search dictionary specifies a way of recognizing interesting or uninteresting words for searching. A dictionary depends on a text search template, which specifies the functions that actually perform the work. Typically the dictionary provides some options that control the detailed behavior of the template’s functions.
如果给出了架构名称，则文本搜索词典会在指定架构中创建。否则，则会在当前架构中创建。
If a schema name is given then the text search dictionary is created in the specified schema. Otherwise it is created in the current schema.
定义文本搜索词典的用户会成为其所有者。
The user who defines a text search dictionary becomes its owner.
