1, which is beneficial to reduce the repeated research of the subject and improve the success rate of scientific research.
Any scientific research is an invention and innovation after inheriting the knowledge of predecessors. Engaged in academic activities in a specific field, it takes a lot of time to conduct a comprehensive investigation and study of relevant literature in order to learn from, improve and deploy their own work.
Only in this way can we think clearly, make discoveries, innovate and make progress, otherwise it will easily lead to repeated work and waste human, material and financial resources.
2. It helps to save time and improve the efficiency of scientific research.
Information retrieval is the foundation and necessary link of research work. Successful information retrieval will undoubtedly save researchers a lot of time and enable them to spend more time and energy on scientific research. Improving the efficiency and speed of scientific research can make the same scientific research subject in a favorable position in the competition at home and abroad.
3. Master the methods of obtaining documents and improve information awareness and information concept.
Learning document retrieval, we should not only learn how to find documents, but also improve our information awareness and information concept, improve our ability to analyze and solve problems independently, and make ourselves have stronger social viability and social competitiveness through the study of this course.

origin
Information retrieval originated from the reference service and abstract index of the library. It first developed in the second half of19th century, and by the 1940s, indexing and retrieval had become an independent tool and user service project of libraries.
With the advent of the first electronic computer in the world in 1946, computer technology gradually entered the field of information retrieval, and was closely combined with information retrieval theory. Off-line batch information retrieval system and online real-time information retrieval system have been successfully developed and commercialized.
From 1960s to 1980s, with the promotion of information processing technology, communication technology, computer and database technology, information retrieval developed rapidly in the fields of education, military and commerce, and was widely used.
Dialog international online information retrieval system is the representative of information retrieval field in this period, and it is still one of the most famous systems in the world.
