I'm not so sure...
Go to this page: http://hshelp.com/search.phtml and try this formula:
vtml and not(attribute or history)
and you'll get (4) results.
Then try this:
"vtml and not(attribute or history)"
and you'll get NO results.
What I'm doing is *not* passing the argument within quotes, but I'm
"escaping" the whole command string.
The reason, of course is that on Unix '(' and ')' are special characters.
Escaping the command string makes sure ALL Unix special characters are
escaped so the complete command is interpreted by Swish. the (PHP)
statements I'm using:
$command = "$swish -w $pattern -m $maxresults -f $index";
exec (EscapeShellCmd($command), $result, $rc);
where $pattern is the exact string typed into the entry field.
BTW, the page I mentioned is for *test* purposes only - don't publish or
link to anywhere please!
I'm mentioning it here only so everyone on the list can see for themselves
that 1) quotes aren't needed (and can in fact lead to undesired results)
and 2) escaping a command string *is* needed - if only to make the system
