How to increase google searching limit?

I have built an Plagiarism Detection application, using Google API and JavaScript which is working fine, but It c开发者_开发百科ould not search when searching material exceeds more than 235 words. Please tell me how to do that.

You can try xgoogle Python lib.

from xgoogle.search import GoogleSearch, SearchError
try:
  gs = GoogleSearch("quick and dirty")
  gs.results_per_page = 50
  results = gs.get_results()
  for res in results:
    print res.title.encode('utf8')
    print res.desc.encode('utf8')
    print res.url.encode('utf8')
    print
except SearchError, e:
  print "Search failed: %s" % e
