The effective strategy for researching the relevant literature mainly depends on the way of searching the literature digitally or using the database. The researchers who perform the search use the bibliographic database initially. While searching use of Keywords or phrases will also help to find the relevant literature. The research design is influenced by the type of questionnaire you are going to introduce in the theory. These theories should be interesting and influencing the whole research you are going to write.(Devine EB et al, 2007)Almost more than 50 articles were got while searching the relevant literature and then sorted out the best that is more relevant to our work.Before searching the appropriate literature it is mandatory to list down the keywords related to that literature and it should be known to us that the literature we will get either of use or not. Atleast the subject knowledge you need beforepreceding anything. Searching by keywords is not much effective instead of it the phrase should be used. (Bucknall T.K. et al, 2006)
研究相关的文献，主要取决于文献检索数字或使用数据库方式的有效策略。研究人员执行搜索最初使用的书目数据库。而搜索使用关键字或短语，也将有助于找到相关的文献。研究设计是通过问卷调查你所要介绍的类型理论的影响。这些理论应该是有趣的整体研究，您将编写和影响。（Devine EB等人，2007）有在搜索相关文献并整理出最好的更多的是有关我们的工作几乎50余篇。在搜索适当的文献必须列出文学相关的关键词，这应该是我们所知的，我们将获得文学的使用或不。至少你需要beforepreceding什么学科知识。搜索的关键词是不是更有效而不是它应该使用的短语。（巴克纳尔T.K.等人，2006）
