There are six databases in SciFinder Scholar, but only four databases appear in the database options, namely, CAPLUS, MEDLINE, REGISTRY and CASREACT, among which MEDLINE database can be selected, while CAPLUS, REGISTRY and CASREACT are all retrieved by default. Because two databases, CHEMLIST and CHEMCAT, can provide few search ways, and because a chemical may be the products of several companies or countries, it is impossible to search uniformly, how are these two databases used? In fact, in SciFinder Scholar, there are two databases, CHEMLIST and CHEMCAT, and the relevant information in these two databases can be obtained through material query. SciFinder Scholar has two main retrieval methods: browsing and browsing. The obtained retrieval results can be refined again or analyzed.
3. 1 browse (search)
Explore can find all the information and structures related to chemistry in five ways.
3. 1. 1 chemical substance or reaction.
The chemical structure can be drawn by the structure drawing software provided by the system, which can obtain the literature information related to substances, the manufacturer information of chemical products, the 3D model of substances (relevant software such as ViewerLite must be installed), the list of controlled important chemicals, reaction information, etc. Through the name of the substance, CAS registration number or molecular formula, the detailed information of the substance and its related literature information can be obtained.
3. 1.2 research topic.
You can search in natural language, and you can limit publication year, document type, document language, author and company name in additional options. After entering search words, the system first displays the candidate list, displays the number of hit results according to different combinations of the entered search words, and selects 1 or more topics of interest to view specific hit records.
3. 1.3 Author's name.
Enter the author's name to retrieve the literature, in which "Last Name" is required and full name must be entered, and "First Name" can be entered as full name or short name.
3. 1.4 file identifier.
Search documents by identification number, such as CA abstract number, patent number, patent application number, PubMed ID, etc.
3. 1.5 company name/organization.
Through the company name/institution search, you can get the literature information related to the research of this institution.
3.2 browse the directory
You can browse the contents of periodicals by their names. The latest issue will be displayed first, and users can choose other issues to browse.
3.3 Refining (secondary retrieval)
In the second search interface, you can search again in the last search result through three search methods (research topic, company name and author name) and five restrictions (publication year, literature type, language, database and full text availability).
3.4 Analysis (Analysis of Search Results)
SciFinder Scholar designed the function of analyzing retrieval results for users. According to the author's name, CAS registration number, CA section title, company/institution, database, literature type, index entry, periodical name, language, publication year and supplementary entry, the retrieval results can be statistically analyzed. Analysis tools can not only make users know more clearly the research status related to this topic, such as which institutions and researchers are engaged in relevant research, but also know which substances, which indexes, which databases, which journals and years these documents are published in these search results. According to the statistical table, you can select the literature that best meets the retrieval requirements from the retrieval results, and further check the detailed information.
