Can I map the number of search matches to a key?

Question

I'd like to map 0 to whatever number of matches I currently have. For example:

This here has 5 matches. If I wanted to perform a macro on every instance, i'd like to be able to simply type:

0Q (Q is remapped as execute macro.)

which would be interpreted as:

5Q

Is this possible? Thanks.

You can use the global command to search for the pattern and then execute a command on the available pattern as such

:global/pattern/command

which could be modified in your case as:

:global/pattern/normal @Q 

where pattern is the word on which you will run the macro and @Q is the macro register.
