OK. I am now using "65832A00.%;1234.%". That also do not work. I think I need to use qs.appendOr();
Below code works. But I have query string which contains 10 or more docs. I am thinking of appending Or condition in a loop. It seems that we can not directly use query string in code.
qs = new QuerySpec(wtDocCls);
SearchCondition sc = new SearchCondition(WTDocument.class, WTDocument.NUMBER, SearchCondition.LIKE, "1234%");
qs.appendWhere(sc);
qs.appendOr();
SearchCondition sc1 = new SearchCondition(WTDocument.class, WTDocument.NUMBER, SearchCondition.LIKE, "65832A00.%");
qs.appendWhere(sc1);
qr = PersistenceHelper.manager.find(qs);
