CREATE TEXT SEARCH TEMPLATE() SQL Commands CREATE TEXT SEARCH TEMPLATE()
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 dic-
tionaries. A template is not useful by itself, but must be instantiated
as a dictionary to be used. The dictionary typically specifies parame-
ters 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 defini-
tion 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 in the documentation 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.
