1. One-box quick search: it can be searched in different databases or across databases according to article title, keywords, author, author unit, journal name and other items. This kind of retrieval can be divided into three categories, namely, literature retrieval, knowledge meta-retrieval and citation retrieval.
Literature retrieval:
For example, enter the keyword "immunity" to search, and there is a filter box on the left side of the search page, where you can add conditions for secondary filtering.
Select the literature type. If you choose journal literature, please click the "Academic Journals" section above.
Knowledge Meta-retrieval: Knowledge Meta-retrieval can retrieve knowledge questions and answers, encyclopedias, dictionaries, manuals, reference books, pictures, statistical data and indexes. Support natural language and keyword questioning, and can automatically mine answers from literature.
Citation retrieval: enter the cited subject, that is, the characteristic words of the cited literature, and you can retrieve it.
2. Advanced retrieval
China HowNet Advanced Search can set multiple search fields and input multiple search terms at the same time. According to Boolean logic ("or, and, not"), defining more search terms-"or contains, contains, does not contain" will get more accurate and smaller search results.
Click the tab of the advanced retrieval page to switch to advanced retrieval, professional retrieval, author post retrieval and sentence retrieval.
Search for Core Journals: Click "Academic Journals" at the bottom of the advanced search page, and then select "Source Category" to search for core journals.
Search for excellent doctoral dissertations: click "Dissertations" under advanced search, and then select the excellent dissertation level.
3. Publication retrieval
On the Publication Retrieval page, enter the name of the journal you want to retrieve.
You can view the details of the journal, including the impact factors.
When the page drops down, you can also search and select the annual log number in the log.
