To count the number of matches of a pattern, use the substitute command with the n flag. The following shows the number of times that pattern matches text in the current buffer:
:%s/pattern//gn
Omit g to display the number of lines where the pattern matches:
:%s/pattern//n
To restrict the count to a region of the text, specify a range instead of % (% means all lines). For example, the following counts the number of occurrences in lines 10 to 50 inclusive:
:10,50s/pattern//gn
The following counts the number of occurrences in the lines in the most recent visual selection.
:'<'>s/pattern//gn
Word under cursor
To count the number of occurrences of the last used search pattern, you can leave out the pattern entirely:
:%s///gn
This makes it easy to count the number of occurrences of the word under the cursor: first press * to search for the current word, then enter :%s///gn to count all occurrences of that word.
