First, put double quotes before and after the sentence to be searched, so that Google can search completely.
Copy the sentence to be searched, enclose it in double quotation marks and put it into Google academic search to find the literature accurately.
Second, use the Litsense website.
If you are a biomedical major, the literature you need to find can be found in pubmed database, and you can use the website Litsense. Most literature databases are based on the logic of keyword search, so when you enter a complete sentence, your sentence will be divided into keywords by default for search.
However, Litsense is a website that searches for papers based on sentences. For example, if you want to find the source of a paper sentence, you just need to enter the sentence directly in the website search bar, and you can find this document directly in the results.
Thirdly, the original source of document sentences can be found from China HowNet.
On the homepage of HowNet, find advanced search and select sentence search.
Extract part of the Chinese paragraph you are looking for and fill it in the search box. If you want to find the source of the original text based on a paragraph, you will change the search requirements to the same paragraph. If you need to search based on a sentence, you can select the content that needs to be included in the same sentence.
