.SH "NAME"
CREATE_TEXT_SEARCH_TEMPLATE \- define a new text search template
.SH "SYNOPSIS"
.sp
.nf
CREATE TEXT SEARCH TEMPLATE \fIname\fR (
    [ INIT = \fIinit_function\fR , ]
    LEXIZE = \fIlexize_function\fR
)
.fi
.SH "DESCRIPTION"
.PP
\fBCREATE TEXT SEARCH TEMPLATE\fR
creates a new text search template\&. Text search templates define the functions that implement text search dictionaries\&. A template is not useful by itself, but must be instantiated as a dictionary to be used\&. The dictionary typically specifies parameters to be given to the template functions\&.
.PP
If a schema name is given then the text search template is created in the specified schema\&. Otherwise it is created in the current schema\&.
.PP
You must be a superuser to use
\fBCREATE TEXT SEARCH TEMPLATE\fR\&. This restriction is made because an erroneous text search template definition could confuse or even crash the server\&. The reason for separating templates from dictionaries is that a template encapsulates the
\(lqunsafe\(rq
aspects of defining a dictionary\&. The parameters that can be set when defining a dictionary are safe for unprivileged users to set, and so creating a dictionary need not be a privileged operation\&.
.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 template to be created\&. The name can be schema\-qualified\&.
.RE
.PP
\fIinit_function\fR
.RS 4
The name of the init function for the template\&.
.RE
.PP
\fIlexize_function\fR
.RS 4
The name of the lexize function for the template\&.
.RE
.PP
The function names can be schema\-qualified if necessary\&. Argument types are not given, since the argument list for each type of function is predetermined\&. The lexize function is required, but the init function is optional\&.
.PP
The arguments can appear in any order, not only the one shown above\&.
.SH "COMPATIBILITY"
.PP
There is no
\fBCREATE TEXT SEARCH TEMPLATE\fR
statement in the SQL standard\&.
.SH "SEE ALSO"
ALTER TEXT SEARCH TEMPLATE (\fBALTER_TEXT_SEARCH_TEMPLATE\fR(7)), DROP TEXT SEARCH TEMPLATE (\fBDROP_TEXT_SEARCH_TEMPLATE\fR(7))
