从谷歌搜索精确短语

Question

我试图用python从google搜索引擎中搜索一些短语。我给输入字符串'DVD player'并用Google搜索包含这两个词的页面，并用DVD+player术语形式化搜索。但我想搜索准确的短语。我试图用"\"DVD plyar\""替换这个词，这样谷歌就可以搜索到"DVD player"，但似乎没有用。在

import urllib.request

    query = urllib.parse.urlencode({'q': searchfor})    
    url = 'http://ajax.googleapis.com/ajax/services/search/web?v=1.0&%s' % query

    search_response = urllib.request.urlopen(url)    
    search_results = search_response.read().decode('utf8')    
    results = json.loads(search_results)    
    data = results['responseData']    
    print ('Total results: %s' % data['cursor']['estimatedResultCount'])

    hits = data['results']    
    print ('Top %d hits:' % len(hits))    
    for h in hits: print (' ', h['url'])

    print ('For more results, see %s' % data['cursor']['moreResultsUrl'])    

showsome("\"DVD player\"")
