Can you improve the "news watches" to include complex relationship between different key words such AND, OR, NOT.
Many thanks.

新闻追踪能不能添加复杂关系的关键字啊,就像某些搜索引擎的高级搜索,可以有多个关键词,每个关键词可以选择匹配单个或所有,各关键词间可以选择 AND OR NOT等关系。
比如我想追踪含有microarray或expression profile两种或更多任一关键字(expression profile为一关键字同时出现)的新闻,现在只能把它们分到两个不同追踪,放到同一追踪里面无法准确定义。当我想过滤掉某些RSS时,更是无法做得到,如果支持逻辑、多个匹配栏目就可以轻松做得到了。
谢谢!
