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.
