Are you speaking of the mechanics on unix or of some other OS,
e.g. Windows?

The mechanics of unix are simple:

Let application A be linked against a shared library with soname S.
At A's runtime, library /usr/lib/S is loaded. There is no "search for
the closest matching library".

Boost uses the convention that has SONAME so the application always loads exactly the
library it was linked with. No heuristics.
