Before run yum remove ceph-release, I would like to look up ceph-release. But quotes like ' and " still brings results like ceph releases, release ceph. So how to look up exactly "ceph-release"?

That was just an example. I would like to know how to look up an exact phrase like "a-b", having punctuation in it.

General case

If you add or remove punctuation characters from a search term Google will often automatically suggest a correction for you.

  1. Example search phrase: air tight
    Google knows what the search term air tight means.

    enter image description here

  2. Example search phrase: fire fly
    Google suggests what is possibly a more exact search term than fire fly.

    enter image description here

  3. Example search phrase: 50/50 returns no useful results, but the more explicit search phrase 50/50 chance does return useful results. Google knows exactly what 50/50 means only if it's made explicit by appending the word chance to the search phrase.

Special case

ceph-release is sometimes enclosed by curly braces to denote whatever release of Ceph (e.g. Hammer, Giant, Firefly, etc.), where the substitution with a particular release should be typed by the user. Google does not seem to know about a ceph-release package.

Search Google for explicit references to a ceph-release package.

package search ceph-release 

Google still does not seem to know about a ceph-release package. Visit Get Packages — Ceph Documentation (the first Google search result) and scroll down to the Add Ceph heading which lists information about all the major Ceph releases.

Google, Yahoo and Bing will all ignore some symbols, even if you use double quotes. SymbolHound does return results with special characters, however searching SymbolHound for ceph-release returns 0 results found for ceph-release.

SymbolHound knows approximately what the search phrase command-line means, but Google knows exactly what command-line means. The first Google search result for command-line explicitly defines it and even provides a screenshot of the command-line interface.

  • I only want to look up "ceph-release" with a hyphen in it, but google returns ceph release. This happens especially lookup up command arguments. So how to make google ceph-release but not ceph release? – Tiina Jun 29 '16 at 9:19
