147884 - Searching in newsgroups fails (XPAT not supported by some news servers)

Status: RESOLVED DUPLICATE of bug 98836

(MailNews Core :: Search, defect)

Description

[ISHIKAWA, Chiaki]

In contrast to older netscape, Mozilla uses
XPAT
command to search for articles, say, a string in a subject line.

Unfortunately, some news servers (such as nntpcache) doesn't support
XPAT yet.
Hence, I can't use the mozilla's search function for, say,
searching news articles for a given string.

I wonder if Mozilla can be modified to
use older netscape-like search function without
using "XPAT" command on user preference request.
(A la the switch between HTTP/1.1 and HTTP/1.0).

I won't mind the reduced functionality when XPAT is not used.

(I know that the use of XPAT probably saves some bandwidth since
the selection of resulting articles is done on the server-side as 
opposed to the client side as in the netscape 4.x  presumably.)

There are a couple existing bugs about this, I'm sure.

I assume that this question is for [e-mail], and not to me,
[e-mail]: I received the inquiry via e-mail from
bugzilla. I wonder if the e-mail was automatically sent to 
[e-mail] as well.

Is this a Dup of Bug 210784

Comment 6

Attachment: This is an image of search subject line of a newsgroup.

Use of XPAT causes an error message from the newsserver.

e comment #5 above, I created attachment mentioned in #6.

Please note the error dialog shown after
I hit SEARCH button.

Right, I can't even use the search with mozilla while
netscape 4.xx works. The news server is nntpcache.
(Maybe I should upgrade the severity.)

I read the mentioned the bug 210784 .

But given that XPAT command doesn't even work against
some newsserver(s), I don't think this is the same
issue.

Obviously, there were attempts by others to implement
"XPAT" command, but it never materialized as far as I can tell.

Is the error dialog authored on the server side?
I use Giganews <www.giganews.com>, which I know does not support XPAT. The error
message I get is:
"A News (NNTP) error occurred: xpat not supported"

Setting this bug as the core problem bug for failing searches on some news servers.
See RFE bug 83968 for the ability of where to search.

It is possible to search locally downloaded headers by switching to "offline" mode.
