# Google Search Results Async in Python

[![Package](https://badge.fury.io/py/google-search-results.svg)](https://badge.fury.io/py/google-search-results)
[![Build](https://github.com/serpapi/google-search-results-python/actions/workflows/python-package.yml/badge.svg)](https://github.com/serpapi/google-search-results-python/actions/workflows/python-package.yml)

This Python package is meant to scrape and parse search results from Google, Bing, Baidu, Yandex, Yahoo, Home depot, Ebay and more.. using [SerpApi](https://serpapi.com). 

The following services are provided:
- [Search API](https://serpapi.com/search-api)
- [Search Archive API](https://serpapi.com/search-archive-api)
- [Account API](https://serpapi.com/account-api)
- [Location API](https://serpapi.com/locations-api) (Google Only)

SerpApi provides a [script builder](https://serpapi.com/demo) to get you started quickly.

## Installation

Python 3.7+
```bash
pip install google-search-results
```

[Link to the python package page](https://pypi.org/project/google-search-results/)

## Quick start

```python
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
- GoogleScholar using GoogleScholarSearch class
- Youtube using YoutubeSearch class
- Walmart using WalmartSearch
- Apple App Store using AppleAppStoreSearch class
- Naver using NaverSearch class

see below for more hands on examples.

### 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:
```python
GoogleSearch.SERP_API_KEY = "Your Private Key"
```
The SerpApi `api_key` can be provided for each search:
```python
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](https://travis-ci.org/serpapi/google-search-results-python) to achieve the best QoS (Quality Of Service).
 
The directory test/ includes specification/examples.

Set your api key.
```bash
export API_KEY="your secret key"
```

Run test
```python
make test
```

### Location API

```python
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)
```python
[   {   '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.

```python
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.

```python
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.

### Search Google News

```python
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

```python
from serpapi import GoogleSearch
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.

```python
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)

```python
# 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.](https://github.com/serpapi/google-search-results-python/blob/master/tests/test_example.py)

### 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.

```python
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.
```python
# 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](https://github.com/serpapi/google-search-results-python/blob/master/tests/test_example_paginate.py), [online IDE](https://replit.com/@DimitryZub1/Scrape-Google-News-with-Pagination-python-serpapi)

### 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.
```python
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.
