Would be cool to filter search public symbols by what a module exports.

For example,

Searching for (guix modules) would show information only for

• missing-dependency-error?
• missing-dependency-module
• missing-dependency-search-path
• file-name->module-name
• module-name->file-name
• source-module-dependencies
• source-module-closure
• live-module-closure
• guix-module-name?

wdyt, or bloat?
