'git ls-files' seems very fast, and moreover it outputs only relative
paths, not absolute.   On TAB completion with too long absolute paths
the list of completions is quite unreadable.

Also is it possible to complete only on file names, not paths?

I think they should mirror everything that makes sense to use in the
multifile project: project-occur, project-grep, ...

Since there is query-replace-regexp, multifile-project-query-replace-regexp
makes sense.

But I don't know to what existing command corresponds 'project-search'?
I tried it on the Emacs source tree, but it failed with:

Debugger entered--Lisp error: (compression-error "Opening input file" "error 
uncompressing empty.zz.gz" "emacs/test/manual/etags/a-src/empty.zz.gz")
