Non-Alphanumeric Characters; Wildcards As Literals - Sun Microsystems Netscape Enterprise Server Administrator's Manual

Non-alphanumeric Characters

You can only search for non-alphanumeric characters if the style.lex file
used to create the collection is set up to recognize them. This file is in the
HTML, news, and mail subdirectories in the server_root\plugins\common\
directory.

Wildcards as Literals

Sometimes you may want to search on characters that are normally used as
wildcards, such as *or ?. To use a wildcard as a literal, you must precede it with
a backslash. In the case of asterisks, you must use two backslashes. For
example, to search on a magazine with a title of Zine***, you would type the
following string:
<WILDCARDZine\\*\\*\\*
Several characters have special meaning for the search engine and require you
to use back quotes to be interpreted as literals. The special search characters
are listed here:
• comma ,
• left and right parentheses ( )
• double quotation mark "
• backslash \
• at sign @
• left curly brace {
• left bracket [
• back quote ` (Note: You can only search on back quotes as literals if the
style.lex file has been set up to recognize it.)
For example, to search for the string "a{b", you would type the following string:
<WILDCARD'a{b'
For another example, if you wanted to search on the string "c`t", which
contains a back quote, you would type the following string:
<WILDCARD'c''t'
