浏览器搜索结果与 Bio.entrez 搜索结果不同

Different result on browser search vs Bio.entrez search

当我使用 Bio Entrez 进行搜索时,我得到了不同的结果。例如,当我使用查询“covid side effect”在浏览器上搜索时,我得到 344 个结果,而当我使用 Bio Entrez 时,我只得到 92 个结果。这是我使用的代码。

from Bio import Entrez
Entrez.email = "Your.Name.Here@example.org"
handle = Entrez.esearch(db="pubmed", retmax=40, term="covid side effect", idtype="acc")
record = Entrez.read(handle)
handle.close()
print(record['Count'])

我希望有人能帮助我解决这个差异。

出于某种原因,无论是 R api 还是 Python API,每个人似乎都有同样的问题。我找到了解决方法以获得相同的结果。它很慢,但可以完成工作。如果您的结果小于 10k,您可以使用 Selenium 来获取 pubmedid。否则,我们可以使用下面的代码来抓取数据。我希望这对以后的人有所帮助。
