iwsrchquery CLT usage

K_SATO

I'm thinking searching contents on the TeamSite with CLT "iwsrchquery".
When I try full-text searching with CLT, I have to create XML queries.
Because of KB and its attachment PDF, now I understand 3 of 4 items on the TeamSite Search GUI, but
I don't know how to create XML for　the term "Without".
Should I use the "<fulltext-wildcard>"?

The followings are my understanding;
------------------------------------
(1) At Least One Word:
<or>
<fulltext-all>
<term>HELLO</term>
</fulltext-all>
<fulltext-all>
<term>WORLD</term>
</fulltext-all>
</or>

(2) Exact Phrase:
<or>
<fulltext-all>
<term>HELLO</term>
</fulltext-all>
</or>

(3)All Words:
<or>
<fulltext-all>
<term>HELLO</term>
<term>WORLD</term>
</fulltext-all>
</or>

(4) Without:
??????

Any ideas????

I'm using TS6.5SP1 on Windows 2000 server.
