Off Topic - . pdf to eps (unknown switch using pdf2ps -eps)

My apologies for so off topic but I feel it is important to have 
choice.  Not intending to change the subject or start a flame war.

It matters because google SEO  pre guesses what it thinks you want 
especially if you have done  a fair bit of searching on a topic. Google 
works well the first time but becomes rapidly restrictive, limiting a 
search to those previous searched pages.
DuckDuckGo and IXQuick do not save previous searches IXQuick has options 
to remove barriers.

I run frequently into this problem when searching for assistance with 
coding examples. Google always presents the same old same old to make 
one's searches easier.
I no longer use google for serious searches because of it's limitations.
Hope this helps.
