Abstract: | Four retrieval methods(without filtering Boolean logic,filtering Boolean logic,filtering natural language and filtering natural language)were used to test seven common databases ASP,GS,JSTOR,LexisNexis,ProQuest Central,PubMed,Scopus,and Web of.Finally,it analyzed that in the current technology environment,Boolean logic and natural language search were more effective than those in natural language retrieval. |
