.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, Full Text Search, in the documentation
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"
