When you search for particular eBooks or specially dummies or PDF files on particular subject, topic and you search in search engine like Google, it crawls every type of files and links which is related with searched keyword.
For example : We have searched for C programming books in google.
If you see the search results above, it has fetched PDF files as well as other links which mayn't contains PDF's.
So, how can we crawl only PDF files then?
Okay,
use filetype:pdf after a search keywords .
Eg: C programming books filetype:pdf
As you can see, when we used filetype:pdf after search keywords, it has only fetched pdf files for us.
By which we can download those eBooks(pdf) as per our requirements.
Okay, that's all. We hope as a student, when you search for specific PDF's for study, you can find if you use this trick. Also let us know your views on this trick on comment section as well.
Stay Positive ! Stay Safe!
Thank you.
