The file also includes references to search macros, such as $$NS-server-url, and
can also refer to other user-defined variables, as in the following lines:
uidir = $$NS-server-url/search-ui
icondir = $$uidir/icons
Search macros are described further in “Macros and Generated Pattern
Variables” on page 444.
You can use any supported HTML character entity in your variable definitions.
You can use entity names that are defined in the
&name ; format as well as
those defined with the three-digit code in the &#nnn ; format. In the
userdefs.ini
code sample, the entity
 
inserts a nonbreaking space
and
©
inserts a copyright symbol. Some of the more commonly used
entities are in the following table:
Configuration File Variables
Some variables are defined in the system configuration and the collection
configuration files. These use a prefix of
NS-
in the configuration file to
differentiate them from other markup tags in an HTML page. To use these
variables as arguments to the search function, you add another prefix
$$
to the
variable, as in
$$NS-date-time
and
$$NS-max-records
.
