NAME

6       CREATE_TEXT_SEARCH_PARSER - define a new text search parser
7

SYNOPSIS

9       CREATE TEXT SEARCH PARSER name (
10           START = start_function ,
11           GETTOKEN = gettoken_function ,
12           END = end_function ,
13           LEXTYPES = lextypes_function
14           [, HEADLINE = headline_function ]
15       )

DESCRIPTION

18       CREATE TEXT SEARCH PARSER creates a new text search parser. A text
19       search parser defines a method for splitting a text string into tokens
20       and assigning types (categories) to the tokens. A parser is not
21       particularly useful by itself, but must be bound into a text search
22       configuration along with some text search dictionaries to be used for
23       searching.
24
25       If a schema name is given then the text search parser is created in the
26       specified schema. Otherwise it is created in the current schema.
27
28       You must be a superuser to use CREATE TEXT SEARCH PARSER. (This
29       restriction is made because an erroneous text search parser definition
30       could confuse or even crash the server.)
31
32       Refer to Chapter 12, Full Text Search, in the documentation for further
33       information.

PARAMETERS

36       name
37           The name of the text search parser to be created. The name can be
38           schema-qualified.
39
40       start_function
41           The name of the start function for the parser.
42
43       gettoken_function
44           The name of the get-next-token function for the parser.
45
46       end_function
47           The name of the end function for the parser.
48
49       lextypes_function
50           The name of the lextypes function for the parser (a function that
51           returns information about the set of token types it produces).
52
53       headline_function
54           The name of the headline function for the parser (a function that
55           summarizes a set of tokens).
56
57       The function names can be schema-qualified if necessary. Argument types
58       are not given, since the argument list for each type of function is
59       predetermined. All except the headline function are required.
60
61       The arguments can appear in any order, not only the one shown above.
62

COMPATIBILITY

64       There is no CREATE TEXT SEARCH PARSER statement in the SQL standard.
