In chapter 3 of Badke’s book I found it interesting how some search engines for some databases use commands just like in some programming languages to find or show certain files except it is a lot simpler. I also have never used none of the commands mentioned in chapter 3 but i think i will incorporate them and make them a habit when I am doing research. Although badke stated a couple commands he also stated that we should look at what other commands certain search engines use like Google. A great example is when Prof.Leonard used the “ti: project x”  to better find works with the title project x.
