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 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.
