CREATE TEXT SEARCH TEMPLATE(7) PostgreSQL 12.3 Documentation CREATE 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.
