While the retrieval of the full-text of a document might seem to end all the hassle of using traditional retrieval systems, the results of the MEDLINE/Full-Text Project indicate that retrieval from the current full-text databases of biomedical journal literature does not match the dream. During the first phase of the project the researchers learned that searching the full-text databases resulted in the retrieval of a significantly larger number of relevant documents than MEDLINE. However, the full-text databases also resulted in a large number of non-relevant documents. Currently the researchers are focusing on how to search these databases to continue retrieving the large number of relevant documents but without so many non-relevant items.
虽然获取文档的全文似乎可以终结使用传统检索系统的所有麻烦，但MEDLINE/全文项目的结果表明，从当前生物医学期刊文献的全文数据库中进行检索并不尽如人意。在该项目的第一阶段，研究人员了解到，在全文数据库中进行检索所得到的相关文档数量比MEDLINE显著更多。然而，全文数据库也产生了大量不相关的文档。目前，研究人员正专注于如何搜索这些数据库，以便继续获取大量相关文档，同时又不会出现如此多的不相关条目。
