Which DB technology is sued to solve the following search issue? : <p>Assume I have built a video sharing site such as youtube, and I want to build a recommendation system.</p>

<p>Assume I have a simple database [ video title, link/url to database ]</p>

<p>Lets assume user watches a video simply tiled - 'Sachin Tendulkar'.
How can I run a query to return me other videos whose search title <code>includes</code> sachin tendulkar ?</p>

<p>eg: other videos could be titled -</p>

<p><code>Straight drive by Sachin Tendulkar</code> or <code>Sachin Tendulkars famous reply to Bret Lee</code>.</p>

<p>In other words, which query can I run to fetch all the videos whose title contains Sachin ?</p>
