CREATE TEXT SEARCH TEMPLATE(7)                  PostgreSQL 9.5.0 Documentation

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, Full Text Search, 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.
