I wanta search several fields use NOT condition, but how?
for example:
I store "test" in {"id", "name", "value", ...} fields.
now I search "test" NOT in "id". That's it.
Can anyone help me?

Alternatively you can use MatchAllDocsQuery, e.g.
BooleanQuery bq = new BooleanQuery();
bq.add(new MatchAllDocsQuery(),Occur.SHOULD);
bq.add(new TermQuery(new Term("id","test")),Occur.MUST_NOT);

You can just add a field to your indexed docs that always evaluates to a
fixed value. Then you can do queries like: +doc:1 -id:test

You will not get any matchs looking for just a boolean NOT-clause. It
has to be combined with something that matches. Perhaps a
MatchAllDocumentsQuery will do it for you.
But to answer your question: a not-query is a Clause of a BooleanQuery.
