CREATE TEXT SEARCH CONFIGURATION — define a new text search configuration
CREATE TEXT SEARCH CONFIGURATIONname
( PARSER =parser_name
| COPY =source_config
)
CREATE TEXT SEARCH CONFIGURATION
creates a new text
search configuration. A text search configuration specifies a text
search parser that can divide a string into tokens, plus dictionaries
that can be used to determine which tokens are of interest for searching.
If only the parser is specified, then the new text search configuration
initially has no mappings from token types to dictionaries, and therefore
will ignore all words. Subsequent ALTER TEXT SEARCH
CONFIGURATION
commands must be used to create mappings to
make the configuration useful. Alternatively, an existing text search
configuration can be copied.
If a schema name is given then the text search configuration is created in the specified schema. Otherwise it is created in the current schema.
The user who defines a text search configuration becomes its owner.
Refer to Chapter 12 for further information.
name
The name of the text search configuration to be created. The name can be schema-qualified.
parser_name
The name of the text search parser to use for this configuration.
source_config
The name of an existing text search configuration to copy.
The PARSER
and COPY
options are mutually
exclusive, because when an existing configuration is copied, its
parser selection is copied too.
There is no CREATE TEXT SEARCH CONFIGURATION
statement
in the SQL standard.
