Search Engine Parser
"If it is a search engine, then it can be parsed" - some random guy
search-engine-parser is a package that lets you query popular search engines and scrape for result titles, links, descriptions and more. It aims to scrape the widest range of search engines. View all supported engines here.
Popular Supported Engines

- DuckDuckGo
- GitHub
- StackOverflow
- Baidu
- YouTube

Usage
Code
Query results can be scraped from popular search engines, as shown in the example snippet below.
import pprint
from search_engine_parser.core.engines.bing import Search as BingSearch
from search_engine_parser.core.engines.google import Search as GoogleSearch
from search_engine_parser.core.engines.yahoo import Search as YahooSearch
search_args = ('preaching to the choir', 1)
gsearch = GoogleSearch()
ysearch = YahooSearch()
bsearch = BingSearch()
gresults = gsearch.search(*search_args)
yresults = ysearch.search(*search_args)
bresults = bsearch.search(*search_args)
a = {
"Google": gresults,
"Yahoo": yresults,
"Bing": bresults
}
# pretty print the result from each engine
for k, v in a.items():
print(f"-------------{k}------------")
for result in v:
pprint.pprint(result)
# print first title from google search
print(gresults["titles"][0])
# print 10th link from yahoo search
print(yresults["links"][9])
# print 6th description from bing search
print(bresults["descriptions"][5])
# print first result containing links, descriptions and title
print(gresults[0])
For localization, you can pass the url
keyword and a localized url. This queries and parses the localized url using the same engine's parser:
# Use google.de instead of google.com
results = gsearch.search(*search_args, url="google.de")
If you need results in a specific language you can pass the 'hl' keyword and the 2-letter country abbreviation (here's a handy list):
# Use 'it' to receive italian results
results = gsearch.search(*search_args, hl="it")
Cache
The results are automatically cached for engine searches. You can either bypass the cache by adding cache=False
to the search
or async_search
method or clear the engine's cache
from search_engine_parser.core.engines.github import Search as GitHub
github = GitHub()
# bypass the cache
github.search("search-engine-parser", cache=False)
#OR
# clear cache before search
github.clear_cache()
github.search("search-engine-parser")
Proxy
Adding a proxy entails sending details to the search function
from search_engine_parser.core.engines.github import Search as GitHub
github = GitHub()
github.search("search-engine-parser",
# http proxies supported only
proxy='http://123.12.1.0',
proxy_auth=('username', 'password'))
Async
search-engine-parser supports async
:
results = await gsearch.async_search(*search_args)
Results
The SearchResults
after searching:
>>> results = gsearch.search("preaching to the choir", 1)
>>> results
<search_engine_parser.core.base.SearchResult object at 0x7f907426a280>
# the object supports retrieving individual results by iteration of just by type (links, descriptions, titles)
>>> results[0] # returns the first <SearchItem>
>>> results[0]["description"] # gets the description of the first item
>>> results[0]["link"] # gets the link of the first item
>>> results["descriptions"] # returns a list of all descriptions from all results
It can be iterated like a normal list to return individual SearchItem
s.
Command line
search-engine-parser comes with a CLI tool known as pysearch
. You can use it as such:
pysearch --engine bing --type descriptions "Preaching to the choir"
Result:
'Preaching to the choir' originated in the USA in the 1970s. It is a variant of the earlier 'preaching to the converted', which dates from England in the late 1800s and has the same meaning. Origin - the full story 'Preaching to the choir' (also sometimes spelled quire) is of US origin.
