I am using the requests library in python to GET
data from google results. https://www.google.com.pk/#q=pizza&num=10 will return first 10 results of google as I mentioned num=10
. Ultimately https://www.google.com.pk/#q=pizza&num=100 will return 100 results of google results.
But
If i write any number more than 100 let https://www.google.com.pk/#q=pizza&num=200 , google is still returning first 100 results
How can I get more than 100 in one pass?
Code:
import requests
url = 'http://www.google.com/search'
my_headers = { 'User-agent' : 'Mozilla/11.0' }
payload = { 'q' : pizza, 'start' : '0', 'num' : 200 }
r = requests.get( url, params = payload, headers = my_headers )
In "r" I am getting only URL's of google first 100 results, not 200
You can use a more programmatic api from google to get the results vs. trying to screen scrape the human search interface, there's no error checking or assertion this is complies with all google T&Cs, suggest you look into the details of using this url:
import requests
def search(query, pages=4, rsz=8):
url = 'https://ajax.googleapis.com/ajax/services/search/web'
params = {
'v': 1.0, # Version
'q': query, # Query string
'rsz': rsz, # Result set size - max 8
}
for s in range(0, pages*rsz+1, rsz):
params['start'] = s
r = requests.get(url, params=params)
for result in r.json()['responseData']['results']:
yield result
E.g. getting 200 results for 'google':
>>> list(search('google', pages=24, rsz=8))
[{'GsearchResultClass': 'GwebSearch',
'cacheUrl': 'http://www.google.com/search?q=cache:y14FcUQOGl4J:www.google.com',
'content': 'Search the world's information, including webpages, images, videos and more. \n<b>Google</b> has many special features to help you find exactly what you're looking\xa0...',
'title': '<b>Google</b>',
'titleNoFormatting': 'Google',
'unescapedUrl': 'https://www.google.com/',
'url': 'https://www.google.com/',
'visibleUrl': 'www.google.com'},
...

To use Google's Custom Search API you need to sign up as a developer. You get 100 free queries (I'm not sure if that is API calls or it allows pagination of the same query to count as 1 query) a day:
key
cx=<cse reference>
)The you can use requests
to make the query:
import requests
url = 'https://www.googleapis.com/customsearch/v1'
params = {
'key': '<key>',
'cx': '<cse reference>',
'q': '<search>',
'num': 10,
'start': 1
}
resp = requests.get(url, params=params)
results = resp.json()['items']
With start
you can do a similar pagination to the above.
There are lots of other parameters available you can look at the REST documentation for the CSE: https://developers.google.com/custom-search/json-api/v1/reference/cse/list#request
Google also has a client-api library: pip install google-api-python-client
you can also use:
from googleapiclient import discovery
service = discovery.build('customsearch', 'v1', developerKey='<key>')
params = {
'q': '<query>',
'cx': '<cse reference>',
'num': 10,
'start': 1
}
query = service.cse().list(**params)
results = query.execute()['items']
