title: Free web search API or web search logs
body: <p>For university research I need a lot of web query examples and the relative resources returned by some search engine, for which I have 2 possibilities: either collect them from a search engine or search some available data set.</p>
  
  <p>I know that Google offers an API but I know that it only permits 100 free queries per day.</p>
  
  <p>Can anyone give me other suggestions?</p>
