Constructing Queries

The search queries I would do is in the example, how could it be life in other planets. I will search it with different tags. The three tags that I would do will be:

• Life in Other Plantes
• Resources are a clue of living things in other planets?
• Aliens

Link º3: http://es.wikipedia.org/wiki/Alien This link wasn't useful because it doesn't provides exact information about what a wanted to look for.

The exact way to look for something you don't know and you only have some words is through tags. The tags is the way in how web pages indicate what should be displayed on the screen when the page loads. Tags are the basic formatting tool used in HTML.

The way to refine the search about life in other planets, I would start to use words that are key to the subject. Doing this, I will be adding more tags that are related to the search I am doing. This will make my search more specific and the pages that appear will be more specific.
