To browse the smallnet you should just point your gemini or gopher client to
the corresponding gemini/gopher server. This is like you would do for the web,
only you don't have google ;)

For instance, try to start from:

  gemini://soviet.circumlunar.space gopher://soviet.circumlunar.space

where you will find pointers to other people's gopherholes/capsules.

For gopher phlogs, you can try one of the aggregators, e.g.:

  gopher://gopher.black/1/moku-pona/ gopher://i-logout.cz/1/bongusta

or have a look at SDF gopherholes:

  gopher://sdf.org/1/phlogs

or Bitreich lawn:

  gopher://bitreich.org/1/lawn

To be fair, there exist also some gemini search engines:

  gemini://gus.guru/
  gemini://houston.coder.town/

and some gopher search engines:

  gopher://gopher.floodgap.com/7/v2/vs  (Veronica)
  gopher://forthworks.com/1/contrition  (Contrition)
