everything fine here....using Mozilla FireFox...
If you have applied SP2 to XP then there's your problem..

After I installed SP2 some pages were(and still are) not found by IE but found by Mozilla FireFox...

This seems to be working fine from here, if you can provide with more details, and give detailed instructions on how to reproduce this, then please feel free to re-open this bug

Go to http://php.net/instanceof , it should bring you to http://www.php.net/manual/en/language.operators.type.php or at least should show the page in the search result.

Ah, I understand what you mean now.

Not sure whether possible for me to fix this, so I'll flag it up as verified for now

actually doesn't the /whatever only reference functions? as instanceof isn't a function it wont be referenced by that. I'm not too sure why the google search isn't picking it up though

Not possible that it only relies on functions. I made a similiar request about http://php.net/php5 and at was promptly done by Derick.

But instanceof is a bitdifferent, as we don't have those hardcoded redirects for any of our control keywords AFAIK.

http://php.net/something is not only for function lookups, there are quite a few shortcuts, like http://php.net/getphp or http://php.net/whatisphp or http://php.net/install and even http://php.net/pear

Look into find_manual_page_slow() in http://php.net/source.php?url=/include/manual-lookup.inc to get an idea of how manual pages are looked up. Reference sections, control structures and other stuff are also matched. If the manual page has a proper ID, then it should end up being found by such a php.net lookup.

instanceof is found at http://www.php.net/manual/en/language.operators.type.php
This will never be catched by find_manual_page_slow().
A possible solution could be a shortcut in error.php like:
$ cvs diff error.php
Index: error.php

What about other names operators? I know they have quite common names like 'and' and 'or' :)

Alias added.
