Well, it's not really a How-to article, but rather a bit of news about what I've been doing very lately.

I created a file search engine by using Google Search API. I first used Google Search API in the past when I wanted to add a bit of content automatically to each pages I created. I was pulling the first 8 results from Google Search API and displaying the title and description of the 8 results, and then lower I was displaying 3 links at random amongst the 8 results.
