I was kinda wondering that myself. There's so many terminal based apps to keep track of, I've gotten into the habit of trying to know a core set fairly well (like bash,awk,sed,grep -P etc). For this sort of thing I have a dozen tabs open in w3m already.

  $ alias wiki='f(){ w3m -F -v "https://en.wikipedia.org/w/index.php?search=${1}&title=Special:Search&ns0=1"; unset -f f; }; f'

  $ wiki pandas

This seemed to work well for me.

A tab to the wikipedia search page bookmarked would work well too and could be used in existing w3m/lynx session.
