Closure

The most important number I had learned from EIR is the effective use of search queries. I think the search query is just like a robot where you have to input your commands into it for it to listen to your commands. A wrong command and you would get a wrong action given it back to you.

Just like in Google.
The wrong search query would results in wrong search results.

I feel this is the most useful lesson to me,
though some parts of the lesson is boring as hell,
overall I enjoyed EIR and I hope others around me enjoyed it as well.
Also learned how to RESEARCH on the INTERNET EFFECTIVELY.
Thank You EIR!
