+.SH "NAME"
+CREATE_TEXT_SEARCH_CONFIGURATION \- define a new text search configuration
+.SH "SYNOPSIS"
+.sp
+.nf
+CREATE TEXT SEARCH CONFIGURATION \fIname\fR (
+ PARSER = \fIparser_name\fR |
+ COPY = \fIsource_config\fR
+)
+.fi
+.SH "DESCRIPTION"
+.PP
+\fBCREATE TEXT SEARCH CONFIGURATION\fR
+creates a new text search configuration\&. A text search configuration specifies a text search parser that can divide a string into tokens, plus dictionaries that can be used to determine which tokens are of interest for searching\&.
+.PP
+If only the parser is specified, then the new text search configuration initially has no mappings from token types to dictionaries, and therefore will ignore all words\&. Subsequent
+\fBALTER TEXT SEARCH CONFIGURATION\fR
+commands must be used to create mappings to make the configuration useful\&. Alternatively, an existing text search configuration can be copied\&.
+.PP
+If a schema name is given then the text search configuration is created in the specified schema\&. Otherwise it is created in the current schema\&.
+.PP
+The user who defines a text search configuration becomes its owner\&.
+.PP
+Refer to
+Chapter\ \&12
+for further information\&.
+.SH "PARAMETERS"
+.PP
+\fIname\fR
+.RS 4
+The name of the text search configuration to be created\&. The name can be schema\-qualified\&.
+.RE
+.PP
+\fIparser_name\fR
+.RS 4
+The name of the text search parser to use for this configuration\&.
+.RE
+.PP
+\fIsource_config\fR
+.RS 4
+The name of an existing text search configuration to copy\&.
+.RE
+.SH "NOTES"
+.PP
+The
+PARSER
+and
+COPY
+options are mutually exclusive, because when an existing configuration is copied, its parser selection is copied too\&.
+.SH "COMPATIBILITY"
+.PP
+There is no
+\fBCREATE TEXT SEARCH CONFIGURATION\fR
+statement in the SQL standard\&.
+.SH "SEE ALSO"
+ALTER TEXT SEARCH CONFIGURATION (\fBALTER_TEXT_SEARCH_CONFIGURATION\fR(7)), DROP TEXT SEARCH CONFIGURATION (\fBDROP_TEXT_SEARCH_CONFIGURATION\fR(7))
