CREATE TEXT SEARCH TEMPLAPostgreSQL 15.7 DocumenCREATE TEXT SEARCH TEMPLATE(7)
NAME
CREATE_TEXT_SEARCH_TEMPLATE - define a new text search template
SYNOPSIS
CREATE TEXT SEARCH TEMPLATE name (
[ INIT = init_function , ]
LEXIZE = lexize_function
)
DESCRIPTION
CREATE TEXT SEARCH TEMPLATE 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.
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.
You must be a superuser to use CREATE TEXT SEARCH TEMPLATE. 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 “unsafe” 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.
Refer to Chapter 12 for further information.
PARAMETERS
name
The name of the text search template to be created. The name can be
schema-qualified.
init_function
The name of the init function for the template.
lexize_function
The name of the lexize function for the template.
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.
The arguments can appear in any order, not only the one shown above.
COMPATIBILITY
There is no CREATE TEXT SEARCH TEMPLATE statement in the SQL standard.
