(A) to avoid repeated research or detours.
(2) Save the time of learning respondents.
(3) It is a shortcut to acquire new knowledge.
Information retrieval is the first step of scientific research, which plays a vital role in the process of scientific research and writing scientific papers. For chemists, it is necessary to master a large amount of chemical information through systematic chemical information retrieval. The traditional manual retrieval method is time-consuming and laborious, and the retrieval is not comprehensive enough, which has been gradually replaced by the rapidly developing network retrieval.
Searching various chemical resources through the Internet has become an important means for chemists to obtain chemical information. The chemical resources on the Internet are very rich. Using the internet to retrieve information is fast, comprehensive and informative, and it takes an hour or two to complete the workload that ordinary people manually consult for half a year.

The selection of database is of great significance and function to the development of information retrieval. Each database has its preferred professional scope, and the common professional scope is as follows:
1, China hownet, CNKI full-text database (China literature).
2. Wanfang Patent Technology Database, VIP ACS and Elsevier Database (English literature).
3. China National Intellectual Property Administration patent retrieval system.
4. Patent retrieval system of China Patent Information Center.
5. Chinese and foreign patent database of National Science and Technology Library.
