Gas, Diesel, Search - The Evolution of the Engine
Everytime I pass through a gasoline station the gasoline boys’ first words are always “Premium or Unleaded”. That was everytime I used a sedan, then one day I borrowed my father’s AUV, an ISUZU Crosswind, and was expecting the same words form the gas boy, to my surprise he just asked me if it would be FULL TANK. I got back to my senses and remembered that I’m using a diesel engine automobile which only had one choice which is diesel. Now we have a third type of Engine, and it has more options than all the previous engines combined but it doesn’t run on fuel rather it runs on data. That is the Search Engine. What? said a jeepney driver. Come again. Can you enlighten me on this one. Okay, I’ll try.
Search engines are sophisticated programs, many of which allow you to search all manner of
files and documents using the same words and phrases you would use in everyday conversations.
On the back end, a search engine is a piece of software that uses applications
to collect information about web pages. The information collected is usually key words or
phrases that are possible indicators of what is contained on the web page as a whole, the URL of
the page, the code that makes up the page, and links into and out of the page. That information
is then indexed and stored in a database.
On the front end, the software has a user interface where users enter a search term — a word or
phrase — in an attempt to find specific information. When the user clicks a search button, an
algorithm then examines the information stored in the back-end database and retrieves links to
web pages that appear to match the search term the user entered.
