[SOLVED] Scraping Oreilly search results with Python returning empty results


This Content is from Stack Overflow. Question asked by Madhur Gupta

I’m using Python to search O’Reilly’s search bar for certain strings but it’s returning empty results.

For example: Here, I’m trying to get O’Reilly’s search bar to give me list of books that it sells related to Science, by appending the string: “Science” to O’Reilly’s Search Bar address: “https://www.oreilly.com/search/?query=” and opening the resulting string: “https://www.oreilly.com/search/?query=Science” through Python’s requests library.

import requests

myurl = "https://www.oreilly.com/search/?query=Science"
page = requests.get(myurl).text

When I look for search results in the resulting html, it has no books in its results.
The book results should ideally come under the tag that goes something like the following:

<section class=”Results–amUWr…

After investigating a bit further, I found that when I print pagethe html result has the following tag (data-search-results=”false”):

<section class=”Results–amUWr” data-search-results=”false”>

However, when I’m pasting the same string (https://www.oreilly.com/search/?query=Science) in a web browser, it’s giving me the above tag as follows:

<section class=”Results–amUWr” data-search-results=”true”>

and the search results are appearing in the browser as well as the html result.

I’m unable to understand why opening the URL through Python is returning me a different result that what happens when I open the URL through a web browser like Chrome. Please help me out regarding this.



Always and first of all check the response to your request or / and your soup.

  • is the request successful?
  • are the expected elements (tags, strings, classes,…) included?

In this case some of them are not, e.g. the content is provided dynamically based on data from an extra POST request – While requests per se is using only the static contents and do not render / manipulate results like a browser would do, you will not be able to process successfully with BeautifulSoup – Cause you could not find_all() what is not available.

You may could simulate browser behavior with selenium and process rendered driver.page_source with BeautifulSoup for practicing purpose, but this is not necessary.

Simply use requests instead and iterate the pages and use the structured data from JSON response to get your expected data:

for i in range(0,10):
    url = f'https://www.oreilly.com/api/v2/search/?query=Science&formats=book&sort=relevance&page={i}'
    books.extend(requests.get(url, headers=headers).json()['results'])


import requests
from bs4 import  BeautifulSoup

headers = {'user-agent': 'Mozilla/5.0'}
books = []

for i in range(0,10):
    url = f'https://www.oreilly.com/api/v2/search/?query=Science&formats=book&sort=relevance&page={i}'
    books.extend(requests.get(url, headers=headers).json()['results'])
