CONFIGURATION(7)			  PostgreSQL 9.2.7 Documentation			ALTER TEXT SEARCH CONFIGURATION(7)

NAME

       ALTER_TEXT_SEARCH_CONFIGURATION - change the definition of a text search configuration

SYNOPSIS

       ALTER TEXT SEARCH CONFIGURATION name
	   ADD MAPPING FOR token_type [, ... ] WITH dictionary_name [, ... ]
       ALTER TEXT SEARCH CONFIGURATION name
	   ALTER MAPPING FOR token_type [, ... ] WITH dictionary_name [, ... ]
       ALTER TEXT SEARCH CONFIGURATION name
	   ALTER MAPPING REPLACE old_dictionary WITH new_dictionary
       ALTER TEXT SEARCH CONFIGURATION name
	   ALTER MAPPING FOR token_type [, ... ] REPLACE old_dictionary WITH new_dictionary
       ALTER TEXT SEARCH CONFIGURATION name
	   DROP MAPPING [ IF EXISTS ] FOR token_type [, ... ]
       ALTER TEXT SEARCH CONFIGURATION name RENAME TO new_name
       ALTER TEXT SEARCH CONFIGURATION name OWNER TO new_owner
       ALTER TEXT SEARCH CONFIGURATION name SET SCHEMA new_schema

DESCRIPTION

       ALTER TEXT SEARCH CONFIGURATION changes the definition of a text search configuration. You can modify its mappings from token types to
       dictionaries, or change the configuration's name or owner.

       You must be the owner of the configuration to use ALTER TEXT SEARCH CONFIGURATION.

PARAMETERS

       name
	   The name (optionally schema-qualified) of an existing text search configuration.

       token_type
	   The name of a token type that is emitted by the configuration's parser.

       dictionary_name
	   The name of a text search dictionary to be consulted for the specified token type(s). If multiple dictionaries are listed, they are
	   consulted in the specified order.

       old_dictionary
	   The name of a text search dictionary to be replaced in the mapping.

       new_dictionary
	   The name of a text search dictionary to be substituted for old_dictionary.

       new_name
	   The new name of the text search configuration.

       new_owner
	   The new owner of the text search configuration.

       new_schema
	   The new schema for the text search configuration.

       The ADD MAPPING FOR form installs a list of dictionaries to be consulted for the specified token type(s); it is an error if there is
       already a mapping for any of the token types. The ALTER MAPPING FOR form does the same, but first removing any existing mapping for those
       token types. The ALTER MAPPING REPLACE forms substitute new_dictionary for old_dictionary anywhere the latter appears. This is done for
       only the specified token types when FOR appears, or for all mappings of the configuration when it doesn't. The DROP MAPPING form removes
       all dictionaries for the specified token type(s), causing tokens of those types to be ignored by the text search configuration. It is an
       error if there is no mapping for the token types, unless IF EXISTS appears.

EXAMPLES

       The following example replaces the english dictionary with the swedish dictionary anywhere that english is used within my_config.

	   ALTER TEXT SEARCH CONFIGURATION my_config
	     ALTER MAPPING REPLACE english WITH swedish;

COMPATIBILITY

       There is no ALTER TEXT SEARCH CONFIGURATION statement in the SQL standard.

DICTIONARY(7) 				   SQL Commands 				   ALTER TEXT SEARCH DICTIONARY(7)

NAME

       ALTER TEXT SEARCH DICTIONARY - change the definition of a text search dictionary

SYNOPSIS

       ALTER TEXT SEARCH DICTIONARY name (
	   option [ = value ] [, ... ]
       )
       ALTER TEXT SEARCH DICTIONARY name RENAME TO newname
       ALTER TEXT SEARCH DICTIONARY name OWNER TO newowner

DESCRIPTION

       ALTER TEXT SEARCH DICTIONARY changes the definition of a text search dictionary. You can change the dictionary's template-specific options,
       or change the dictionary's name or owner.

       You must be the owner of the dictionary to use ALTER TEXT SEARCH DICTIONARY.

PARAMETERS

       name   The name (optionally schema-qualified) of an existing text search dictionary.

       option The name of a template-specific option to be set for this dictionary.

       value  The new value to use for a template-specific option.  If the equal sign and value are omitted, then any  previous  setting  for  the
	      option is removed from the dictionary, allowing the default to be used.

       newname
	      The new name of the text search dictionary.

       newowner
	      The new owner of the text search dictionary.

       Template-specific options can appear in any order.

EXAMPLES

       The following example command changes the stopword list for a Snowball-based dictionary. Other parameters remain unchanged.

       ALTER TEXT SEARCH DICTIONARY my_dict ( StopWords = newrussian );

       The following example command changes the language option to dutch, and removes the stopword option entirely.

       ALTER TEXT SEARCH DICTIONARY my_dict ( language = dutch, StopWords );

       The following example command ``updates'' the dictionary's definition without actually changing anything.

       ALTER TEXT SEARCH DICTIONARY my_dict ( dummy );

       (The  reason  this  works  is that the option removal code doesn't complain if there is no such option.) This trick is useful when changing
       configuration files for the dictionary: the ALTER will force existing database sessions to re-read the configuration files, which otherwise
       they would never do if they had read them earlier.

COMPATIBILITY

       There is no ALTER TEXT SEARCH DICTIONARY statement in the SQL standard.
