CREATE TEXT SEARCH PARSEPostgreSQL 9.6.3 DocumentaCREATE TEXT SEARCH PARSER(7)

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, Full Text Search, 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.
