Managing Tweepy API Search

问题:

Please forgive me if this is a gross repeat of a question previously answered elsewhere, but I am lost on how to use the tweepy API search function. Is there any documentation available on how to search for tweets using the api.search() function?

Is there any way I can control features such as number of tweets returned, results type etc.?

The results seem to max out at 100 for some reason.

the code snippet I use is as follows

searched_tweets = self.api.search(q=query,rpp=100,count=1000)

I originally worked out a solution based on Yuva Raj's suggestion to use additional parameters in GET search/tweets - the max_id parameter in conjunction with the id of the last tweet returned in each iteration of a loop that also checks for the occurrence of a TweepError.

However, I discovered there is a far simpler way to solve the problem using a tweepy.Cursor (see tweepy Cursor tutorial for more on using Cursor).

The following code fetches the most recent 1000 mentions of 'python'.

import tweepy
# assuming twitter_authentication.py contains each of the 4 oauth elements (1 per line)
from twitter_authentication import API_KEY, API_SECRET, ACCESS_TOKEN, ACCESS_TOKEN_SECRET

auth = tweepy.OAuthHandler(API_KEY, API_SECRET)
auth.set_access_token(ACCESS_TOKEN, ACCESS_TOKEN_SECRET)

api = tweepy.API(auth)

query = 'python'
max_tweets = 1000
searched_tweets = [status for status in tweepy.Cursor(api.search, q=query).items(max_tweets)]

Update: in response to Andre Petre's comment about potential memory consumption issues with tweepy.Cursor, I'll include my original solution, replacing the single statement list comprehension used above to compute searched_tweets with the following:

searched_tweets = []
last_id = -1
while len(searched_tweets) < max_tweets:
    count = max_tweets - len(searched_tweets)
    try:
        new_tweets = api.search(q=query, count=count, max_id=str(last_id - 1))
        if not new_tweets:
            break
        searched_tweets.extend(new_tweets)
        last_id = new_tweets[-1].id
    except tweepy.TweepError as e:
        # depending on TweepError.code, one may want to retry or wait
        # to keep things simple, we will give up on an error
        break

There's a problem in your code. Based on Twitter Documentation for GET search/tweets,

The number of tweets to return per page, up to a maximum of 100. Defaults to 15. This was   
formerly the "rpp" parameter in the old Search API.

Your code should be,

CONSUMER_KEY = '....'
CONSUMER_SECRET = '....'
ACCESS_KEY = '....'
ACCESS_SECRET = '....'

auth = tweepy.auth.OAuthHandler(CONSUMER_KEY, CONSUMER_SECRET)
auth.set_access_token(ACCESS_KEY, ACCESS_SECRET)
api = tweepy.API(auth)
search_results = api.search(q="hello", count=100)

for i in search_results:
    # Do Whatever You need to print here

The other questions are old and the API changed a lot.

Easy way, with Cursor (see the Cursor tutorial). Pages returns a list of elements (You can limit how many pages it returns. .pages(5) only returns 5 pages):

for page in tweepy.Cursor(api.search, q='python', count=100, tweet_mode='extended').pages():
    # process status here
    process_page(page)

Where q is the query, count how many will it bring for requests (100 is the maximum for requests) and tweet_mode='extended' is to have the full text. (without this the text is truncated to 140 characters) More info here. RTs are truncated as confirmed jaycech3n.

If you don't want to use tweepy.Cursor, you need to indicate max_id to bring the next chunk. See for more info.

last_id = None
result = True
while result:
    result = api.search(q='python', count=100, tweet_mode='extended', max_id=last_id)
    process_result(result)
    # we subtract one to not have the same again.
    last_id = result[-1]._json['id'] - 1
