CREATE TEXT SEARCH TEMPLATE

define a new text search template

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 [???](#textsearch) 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.
