I am running opensuse Leap 42 on my laptop and the search functionality is absolutely amazing. It not just searches for the file names but also the content, which is really useful when you have a lot of lectures in pdf form.
My girlfriend has a ubuntu gnome installed on her laptop, and I recently realized that the standard search will only look for file names not the content of the files.
I have two short questions: 1. Can I somehow change the ubuntu gnome search to also look inside the pdf files.
On opensuse, can I change the search field to start a search on youtube.com or wikipedia.org when specific keywords are used. "wi The americans" should pop up firefox and give me a wikipedia search for "The americans"
The search in gnome-shell uses tracker. You can change the preferences for indexing with tracker-preferences which is included in the package tracker-gui on Debian and Ubuntu.
But i am not sure if you can search for content with gnome shells search after that. I think it explicitly asks tracker for file names only. There are some extensions that integrate direct tracker search in the shell. But i don't know how well they work: Tracker Search, Tracker Search Provider
Other than that a good search for content of files is DocFetcher but the GUI is not the most beautiful.
Newer, simpler and pretty fast apps for searching Everything is ANGRYsearch and fsearch.
For web searches just search on extensions.gnome.org for wikipedia, youtube or other sites. There are different extensions that do the job.
