Search Engine Tips搜索引擎的秘诀

A visitor to the site recently searched for the following游客到该网站最近搜索了以下

“control OR system OR health OR care OR new OR research OR high OR science OR product” “控制或系统或健康或照顾或新或研究，或高或科学或产品”

Now anyone who has used any search engine successfully will spot the fatal flaw in such a search.现在，只要谁用任何搜寻引擎成功地将现场致命的缺陷，在这样一个搜索。 I’ve no idea whether the person was looking for control, system, health, care, new, research, high, science, product, or what.我已经不知道该人是否正在寻找控制，系统，保健，护理，新的研究，高，科学，产品或什么。

I suspect what they were after was information on scientific research into healthcare control system products.我怀疑什么，他们的资料后，是对科研医疗保健控制系统的产品。 But, I could be mistaken.不过，我可能被误。 If I’m right though, then the search string they should have used would be something like this:如果我的权利，虽然，然后搜寻字串，他们应该使用会是这样的：

“scientific research” “healthcare control system” products “科学研究” ， “医疗保健控制系统”产品

To be strict and depending on the search engine they might have used the Boolean “AND” (Certainly not the “OR”) to make their search tighter:要严格依赖于搜索引擎，他们可能会使用布尔“和” （当然不是“或” ） ，使他们的搜索更严格的：

“scientific research” AND “healthcare control system” AND products “科研”和“卫生保健控制系统”及产品

There are lots of variations one might use, Google prefers a + sign for terms that really, really must be used in the search so that even noise words can be included有很多的变化之一，可能使用时， Google喜欢一个+号为条件，真的，真的必须使用在搜索，使噪音的话，甚至可以包括

+”scientific research” +”healthcare control system” +products + “科研” + “保健控制系统” +产品

The only trouble with using the term products is it’s more likely to take you to consumer type sites rather than scientific research sites, much better to search for such things on techxtra, intute, googlescholar etc using David Bradley’s science search box available from Sciencebase or on sites such as唯一的麻烦与使用的产品来说，是它的更可能带你到消费型网站，而不是科研网站，更要搜索这类事情就techxtra ，因图泰， googlescholar等使用大卫布拉德利的科学搜索框可用从sciencebase或网站上，如 IRN irn (It’s below the “fold” on the left hand side). （它的下面“倍”就在左手边） 。
