Doesn't scrape oolder tweets

[Altrastorique]

Yesturday my code scraped 5407 tweets containing the word '$MASK' the 25/06/2025. Now I ran the same code today and scraped only 4 tweet the 25/06/2025.
Is this normal?
Here is my code:

START_DATE = "2025-06-23"
END_DATE = "2025-07-01"
KEYWORDS = ["catwifmask", "$MASK"]
QUERY = f'({" OR ".join(KEYWORDS)}) since:{START_DATE} until:{END_DATE}'
print(QUERY)


async def main():
    api = API()
    await api.pool.login_all()

    count_by_day = defaultdict(int)
    score_by_day = defaultdict(int)

    count_by_hour = defaultdict(int)
    score_by_hour = defaultdict(int)

    influencer_scores = defaultdict(int)
    tweet_urls_by_user = defaultdict(list)

    async for tweet in api.search(QUERY): 
        if not tweet.date:
            print("skipped tweet because it had no tweet.date")
            continue
        if not any(term.lower() in tweet.rawContent.lower() for term in KEYWORDS): <-I made this to avoid tweets containg the keyword only in comment
            print(f"Skipped tweet because of RawContent")
            continue  # Skip tweets that don’t explicitly contain one of the keywords

        dt = tweet.date
        d = dt.date()
        h = dt.replace(minute=0, second=0, microsecond=0)  # truncate to hour

        if not (date.fromisoformat(START_DATE) <= d < date.fromisoformat(END_DATE)):
            print("skipped tweet because dates are not matching")
            continue

        #tweet_score = tweet.user.followersCount * 0.05 + tweet.likeCount
        tweet_score =  tweet.user.followersCount * 0.1 + tweet.retweetCount * 50 + tweet.likeCount * 10
        count_by_day[d] += 1
        score_by_day[d] += tweet_score

        count_by_hour[h] += 1
        score_by_hour[h] += tweet_score

        influencer_scores[tweet.user.username] += tweet_score

        url = f"https://twitter.com/{tweet.user.username}/status/{tweet.id}"
        tweet_urls_by_user[tweet.user.username].append(url)

Thank you very much for any help
