8 <code class="command">CREATE TEXT SEARCH CONFIGURATION</code> creates a new text
9 search configuration. A text search configuration specifies a text
10 search parser that can divide a string into tokens, plus dictionaries
11 that can be used to determine which tokens are of interest for searching.
13 If only the parser is specified, then the new text search configuration
14 initially has no mappings from token types to dictionaries, and therefore
15 will ignore all words. Subsequent <code class="command">ALTER TEXT SEARCH
16 CONFIGURATION</code> commands must be used to create mappings to
17 make the configuration useful. Alternatively, an existing text search
18 configuration can be copied.
20 If a schema name is given then the text search configuration is created in
21 the specified schema. Otherwise it is created in the current schema.
23 The user who defines a text search configuration becomes its owner.
25 Refer to <a class="xref" href="textsearch.html" title="Chapter 12. Full Text Search">Chapter 12</a> for further information.
