4、一些高级技巧

Science Direct 高级技巧

1 为什么要注册
注册后就可以享受一些服务,比如my 提醒)的功能,可以储存检索策略,当有新的符合你要求的文献出现以后,可以通过电子邮件提醒你.
在比如检索历史,也需要注册后才享有,你可以查看检索历史,并且可以将已经有的检索词用布尔算符连起来检索.
2 sd 的限制字段
Journal-Name,title,authors,references,abstracts,keywords,text,full-text
格式:authors(benabid) ,keywords(epilepsy)
如果不限制的话，所输入的词可以位于作者，标题，文摘，参考文献，正文中．
3 sd的 LexisNexis逻辑算符
1)尽量使用最贴切的词,也要考虑同义词,近义词,缩写词等
如:kidney disease OR renal failure,mri OR magnetic resonance imaging.
2)作者检索姓一定要给出全称,推荐authors (姓 W/3 某字母）
　如：authors(benabid w/3 a)其结果包括Benabid A L,A L Benabid, Benabid A,
其中的w 表示在benabid 和a 之间可以有３个words,
3)截词符号！，可以截多个词，使用＊截单个词
　如cit!将会找到city,cities,city's
4)stop words遇到下列词时系统不会检索，冠词（a,an ,the ),代词（i,you ,he等），系动词（is ,be,are),连词（if ,then ,because等)
　如keywords(profit and loss),系统将检索词组profit loss
5)其他语法：
　NOT W/n,出现该词，但是不在n个词以内
　PRE/nn，该词位于位于前n个词以内
　W/SEG，两词位于相同的限制性字段内
６）各个语法的有限运算顺序,使用括号可以改变顺序
OR
W/nn
PRE/nn
NOT W/nn
W/SEG
NOT W/SEG
AND
AND NOT
例如：pain W/15 morphine AND ganglia OR tumor OR　lesion W/5 malignant
检索的顺序：１）含有ganglia ，lesion ,tumor等词
２）与lesion 在５各词以内的词maligant
３）pain 及与morphine在１５个词以内
７）其他：希腊字母，数字，其他语种文字转成英文，连词符号取消，
如K（kappa),2(two),Fürst(Furst),high-risk(high risk)
