NAME

6       CREATE_TEXT_SEARCH_TEMPLATE - define a new text search template
7

SYNOPSIS

9       CREATE TEXT SEARCH TEMPLATE name (
10           [ INIT = init_function , ]
11           LEXIZE = lexize_function
12       )

DESCRIPTION

15       CREATE TEXT SEARCH TEMPLATE creates a new text search template. Text
16       search templates define the functions that implement text search
17       dictionaries. A template is not useful by itself, but must be
18       instantiated as a dictionary to be used. The dictionary typically
19       specifies parameters to be given to the template functions.
20
21       If a schema name is given then the text search template is created in
22       the specified schema. Otherwise it is created in the current schema.
23
24       You must be a superuser to use CREATE TEXT SEARCH TEMPLATE. This
25       restriction is made because an erroneous text search template
26       definition could confuse or even crash the server. The reason for
27       separating templates from dictionaries is that a template encapsulates
28       the “unsafe” aspects of defining a dictionary. The parameters that can
29       be set when defining a dictionary are safe for unprivileged users to
30       set, and so creating a dictionary need not be a privileged operation.
31
32       Refer to Chapter 12 for further information.

PARAMETERS

35       name
36           The name of the text search template to be created. The name can be
37           schema-qualified.
38
39       init_function
40           The name of the init function for the template.
41
42       lexize_function
43           The name of the lexize function for the template.
44
45       The function names can be schema-qualified if necessary. Argument types
46       are not given, since the argument list for each type of function is
47       predetermined. The lexize function is required, but the init function
48       is optional.
49
50       The arguments can appear in any order, not only the one shown above.
