Ignore possible matches value

In the window "Window"> "Settings"> "General"> "Search" there is an option "Ignore potential matches"

What is he doing? Whether I activate it or not, I never see the difference.

Is this an option that only makes sense for Java development (which I never do, but I'm developing in C, Python, and PHP using Eclipse)?

See bug 127442 for examples: depending on what you are looking for (class, method, ...), the search engine may find instances that might match (but it cannot be said for sure).

These instances are marked with " ": POTENTIAL_MATCH
