NAME
       CREATE TEXT SEARCH PARSER - define a new text search parser


SYNOPSIS
       CREATE TEXT SEARCH PARSER name (
           START = start_function ,
           GETTOKEN = gettoken_function ,
           END = end_function ,
           LEXTYPES = lextypes_function
           [, HEADLINE = headline_function ]
       )


DESCRIPTION
       CREATE TEXT SEARCH PARSER creates a new text search parser. A text search parser defines a method for splitting
       a text string into tokens and assigning types (categories) to the tokens.  A parser is not particularly  useful
       by  itself,  but  must be bound into a text search configuration along with some text search dictionaries to be
       used for searching.

       If a schema name is given then the text search parser is created in the specified schema. Otherwise it is  cre-
       ated in the current schema.

       You  must be a superuser to use CREATE TEXT SEARCH PARSER.  (This restriction is made because an erroneous text
       search parser definition could confuse or even crash the server.)

       Refer to in the documentation for further information.

PARAMETERS
       name   The name of the text search parser to be created. The name can be schema-qualified.

       start_function
              The name of the start function for the parser.

       gettoken_function
              The name of the get-next-token function for the parser.

       end_function
              The name of the end function for the parser.

       lextypes_function
              The name of the lextypes function for the parser (a function that returns information about the  set  of
              token types it produces).

       headline_function
              The name of the headline function for the parser (a function that summarizes a set of tokens).

       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. All except the headline function are required.


       The arguments can appear in any order, not only the one shown above.


COMPATIBILITY
       There is no CREATE TEXT SEARCH PARSER statement in the SQL standard.
