DBsight 1.5.5 (Default branch)
Image DBSight is a J2EE search platform for instant scalable full-text search on any relational database, for both beginners and experts. It features a built-in database crawler following user-defined SQL, incremental indexing, user-controllable result ranking, the ability to return results with highlights (like Google), and categorized result counts (like Amazon). It can easily integrate with other languages with XML/JSON/HTML. There is a UI for all operations, so no Java coding is necessary. Deleted or updated records in database can be synchronized also. License: Free for non-commercial use Changes:
Regular expression search has been added. Time-based ranking has been added for sortBy=_relevance_ during searching. Reserved Words have been added to bypass analyzers. Javadoc for writing JSP templates has been fixed. Time-based ranking has been improved. Duplication deletion performance has been improved. A bug in reserved words with the analyzer has been fixed. Possible hanging during shutdown has been fixed. This release handles unpaired double quotes in the user search string.Image

ALTER TEXT SEARCH 
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.
