I have tried gitk $(git log -S" extreemly rare " --pretty=format:%h), as this answer suggests  but gitk shows all commits in addition to the search results (if I can add anything to a universal set)
Initially, this came from this answer, that recommended gitk --all $(git log -S" rare text" --pretty=format:%h). I was advised to remove --all but this does not have any effect.
