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 Chapter 12 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.
