Customizing the Search Interface
438 Netscape Enterprise Server Administrator’s Guide
You can set up a search to use a variable conditionally so that if there is no
value associated with the variable, nothing is displayed. The syntax is as
follows:
variableName[conditionalized output]
For example, you could request that the document’s title be output if it exists. If
there is no title for this document, not even the label “Title:” is to be displayed.
To do this, you would use code like this:
$$Title[<PTitle: <B$$Title</B]
URL Encodings
When you construct HTML instructions, whether in decorated URLs or within a
pattern file, you need to follow the rules for URL encoding. Any character that
might be misunderstood as part of an URL should be encoded with a code in
the format of
%nn , where nn is a hexadecimal code. Blanks are converted to
the + symbol (plus sign) in queries or to %20 in output. The following table
shows the most commonly used URL codes.
