Google Search Results Async in Python

This Python package is meant to scrape and parse search results from Google, Bing, Baidu, Yandex, Yahoo, Home depot, Ebay and more.. using SerpApi.

The following services are provided:

• Search API
• Search Archive API
• Account API
• Location API (Google Only)

SerpApi provides a script builder to get you started quickly.

Installation

Python 3.7+

pip install google-search-results

Link to the python package page

Quick start

from serpapi import GoogleSearch
search = GoogleSearch({
    "q": "coffee", 
    "location": "Austin,Texas",
    "api_key": "<your secret api key>"
  })
result = search.get_dict()

This example runs a search about "coffee" using your secret api key.

The SerpApi service (backend)

• searches on Google using the search: q = "coffee"
• parses the messy HTML responses
• return a standardizes JSON response The GoogleSearch class
• Format the request
• Execute GET http request against SerpApi service
• Parse JSON response into a dictionary Et voila..

Alternatively, you can search:

• Bing using BingSearch class
• Baidu using BaiduSearch class
• Yahoo using YahooSearch class
• duckduckgo using DuckDuckGoSearch class
• Ebay using EbaySearch class
• Yandex using YandexSearch class
• HomeDepot using HomeDepotSearch class

How to set SERP API key

You can get an API key here if you don't already have one: https://serpapi.com/users/sign_up

The SerpApi api_key can be set globally:

GoogleSearch.SERP_API_KEY = "Your Private Key"

The SerpApi api_key can be provided for each search:

query = GoogleSearch({"q": "coffee", "serp_api_key": "Your Private Key"})

Example by specification

We love true open source, continuous integration and Test Drive Development (TDD). We are using RSpec to test our infrastructure around the clock to achieve the best QoS (Quality Of Service).

The directory test/ includes specification/examples.

Set your api key.

export API_KEY="your secret key"

Run test

make test

Location API

from serpapi import GoogleSearch
search = GoogleSearch({})
location_list = search.get_location("Austin", 3)
print(location_list)

it prints the first 3 location matching Austin (Texas, Texas, Rochester)

[   {   'canonical_name': 'Austin,TX,Texas,United States',
        'country_code': 'US',
        'google_id': 200635,
        'google_parent_id': 21176,
        'gps': [-97.7430608, 30.267153],
        'id': '585069bdee19ad271e9bc072',
        'keys': ['austin', 'tx', 'texas', 'united', 'states'],
        'name': 'Austin, TX',
        'reach': 5560000,
        'target_type': 'DMA Region'},
        ...]

Search Archive API

The search result are stored in temporary cached. The previous search can be retrieve from the the cache for free.

from serpapi import GoogleSearch
search = GoogleSearch({"q": "Coffee", "location": "Austin,Texas"})
search_result = search.get_dictionary()
assert search_result.get("error") == None
search_id = search_result.get("search_metadata").get("id")
print(search_id)

Now let retrieve the previous search from the archive.

archived_search_result = GoogleSearch({}).get_search_archive(search_id, 'json')
print(archived_search_result.get("search_metadata").get("id"))

it prints the search result from the archive.

        print("link: " + link)
        # wget.download(link, '.')
    except:
        pass

this code prints all the images links, and download image if you un-comment the line with wget (linux/osx tool to download image).

This tutorial covers more ground on this topic. https://github.com/serpapi/showcase-serpapi-tensorflow-keras-image-training

Search Google News

from serpapi import GoogleSearch
search = GoogleSearch({
    "q": "coffe",   # search search
    "tbm": "nws",  # news
    "tbs": "qdr:d", # last 24h
    "num": 10
})
for offset in [0,1,2]:
    search.params_dict["start"] = offset * 10
    data = search.get_dict()
    for news_result in data['news_results']:
        print(str(news_result['position'] + offset * 10) + " - " + news_result['title'])

this script prints the first 3 pages of the news title for the last 24h.

Search Google Shopping

search = GoogleSearch({
    "q": "coffe",   # search search
    "tbm": "shop",  # news
    "tbs": "p_ord:rv", # last 24h
    "num": 100
})
data = search.get_dict()
for shopping_result in data['shopping_results']:
    print(shopping_result['position']) + " - " + shopping_result['title'])

this script prints all the shopping results order by review order.

Google Search By Location

With SerpApi, we can build Google search from anywhere in the world. This code is looking for the best coffee shop per city.

from serpapi import GoogleSearch
for city in ["new york", "paris", "berlin"]:
  location = GoogleSearch({}).get_location(city, 1)[0]["canonical_name"]
  search = GoogleSearch({
      "q": "best coffee shop",   # search search
      "location": location,
      "num": 1,
      "start": 0
  })
  data = search.get_dict()
  top_result = data["organic_results"][0]["title"]

Batch Asynchronous Searches

We do offer two ways to boost your searches thanks to async parameter.

• Blocking - async=false - it's more compute intensive because the search would need to hold many connections. (default)
• Non-blocking - async=true - it's way to go for large amount of query submitted by batch (recommended)

# Operating system
import os

# regular expression library
import re

# safe queue (named Queue in python2)
from queue import Queue

# Time utility
import time

# SerpApi search
from serpapi import GoogleSearch

# store searches
search_queue = Queue()

# SerpApi search
search = GoogleSearch({
    "location": "Austin,Texas",
    "async": True,
    "api_key": os.getenv("API_KEY")
})

# loop through a list of companies
for company in ['amd', 'nvidia', 'intel']:
    print("execute async search: q = " + company)
    search.params_dict["q"] = company
    result = search.get_dict()
    if "error" in result:
        print("oops error: ", result["error"])
        continue
    print("add search to the queue where id: ", result['search_metadata'])
    # add search to the search_queue
    search_queue.put(result)

print("wait until all search statuses are cached or success")

# Create regular search
while not search_queue.empty():
    result = search_queue.get()
    search_id = result['search_metadata']['id']

    # retrieve search from the archive - blocker
    print(search_id + ": get search from archive")
    search_archived = search.get_search_archive(search_id)
    print(search_id + ": status = " +
          search_archived['search_metadata']['status'])

    # check status
    if re.search('Cached|Success',
                 search_archived['search_metadata']['status']):
        print(search_id + ": search done with q = " +
              search_archived['search_parameters']['q'])
    else:
        # requeue search_queue
        print(search_id + ": requeue search")
        search_queue.put(result)

        # wait 1s
        time.sleep(1)

print('all searches completed')

This code shows how to run searches asynchronously. The search parameters must have {async: True}. This indicates that the client shouldn't wait for the search to be completed. The current thread that executes the search is now non-blocking which allows to execute thousand of searches in seconds. The SerpApi backend will do the processing work. The actual search result is defer to a later call from the search archive using get_search_archive(search_id). In this example the non-blocking searches are persisted in a queue: search_queue. A loop through the search_queue allows to fetch individual search result. This process can be easily multithreaded to allow a large number of concurrent search requests. To keep thing simple, this example does only explore search result one at a time (single threaded).

See example.

Python object as a result

The search results can be automatically wrapped in dynamically generated Python object. This solution offers a more dynamic solution fully Oriented Object Programming approach over the regular Dictionary / JSON data structure.

from serpapi import GoogleSearch
search = GoogleSearch({"q": "Coffee", "location": "Austin,Texas"})
r = search.get_object()
assert type(r.organic_results), list
assert r.organic_results[0].title
assert r.search_metadata.id
assert r.search_metadata.google_url
assert r.search_parameters.q, "Coffee"
assert r.search_parameters.engine, "google"

Pagination using iterator

Let's collect links accross multiple search result pages.

# to get 2 pages
start = 0
end = 40
page_size = 10

# basic search parameters
parameter = {
  "q": "coca cola",
  "tbm": "nws",
  "api_key": os.getenv("API_KEY"),
  # optional pagination parameter
  #  the pagination method can take argument directly
  "start": start,
  "end": end,
  "num": page_size
}

# as proof of concept 
# urls collects
urls = []

# initialize a search
search = GoogleSearch(parameter)

# create a python generator using parameter
pages = search.pagination()
# or set custom parameter
pages = search.pagination(start, end, page_size)

# fetch one search result per iteration 
# using a basic python for loop 
# which invokes python iterator under the hood.
for page in pages:
  print(f"Current page: {page['serpapi_pagination']['current']}")
  for news_result in page["news_results"]:
    print(f"Title: {news_result['title']}\nLink: {news_result['link']}\n")
    urls.append(news_result['link'])
  
# check if the total number pages is as expected
# note: the exact number if variable depending on the search engine backend
if len(urls) == (end - start):
  print("all search results count match!")
if len(urls) == len(set(urls)):
  print("all search results are unique!")

Examples to fetch links with pagination: test file, online IDE

Error management

SerpAPI keeps error mangement very basic.

• backend service error or search fail
• client error

If it's a backend error, a simple message error is returned as string in the server response.

from serpapi import GoogleSearch
search = GoogleSearch({"q": "Coffee", "location": "Austin,Texas", "api_key": "<secret_key>"})
data = search.get_json()
assert data["error"] == None

In some case, there is more details availabel in the data object.

If it's client error, then a SerpApiClientException is raised.

Conclusion

SerpApi supports all the major search engines. Google has the more advance support with all the major services available: Images, News, Shopping and more.. To enable a type of search, the field tbm (to be matched) must be set to:

• isch: Google Images API.
• nws: Google News API.
• shop: Google Shopping API.
• any other Google service should work out of the box.
• (no tbm parameter): regular Google search.

The field tbs allows to customize the search even more.
