CREATE TEXT SEARCH PARSER()      SQL Commands      CREATE TEXT SEARCH PARSER()



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 (cate-
       gories)  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 created 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.
