[Zope] keyword index and netscape vs ie

[Jonathan Cheyne]

Hi all.

I am using a keyword index as per the excellent howto. I use the
following snippet to list the keywords as a series of links to further
searches. (this is the objects index_html)

related topics:
<dtml-in keywords>
<a href="search?key=<dtml-var sequence-item>"><dtml-var
sequence-item></a><br>
</dtml-in>

This works fantastic if you are using IE or a keyword is just one word.
Netscape does not seem to do anything intelligent if it is a key phrase
instead and returns an error. Below are examples of the resolved urls it
is trying to load

IE                 .../search?key=direct%20access
Netscape       .../search?key=direct access

Explorer pads out with the %20 - netscape does not - in fact netscape
only works if a + appears instead. Netscape and Explorer  add the +  if
a form field is used instead (similar to that at the top of the zope
site etc)

So my question to the gurus is is there an attribute or expression I can
use to get round this? How can I specify that the two (or more) words in
a keyword phrase are separated by pluses when the link is generated?

yours in hope
