Vim's standard search commands are / for forward search and ? for backward search.
To start a search from normal mode:
/,<CR> to perform the search.Examples:
/foobar<CR> search forward for foobar
?foo\/bar<CR> search backward for foo/bar
n and N can be used to jump to the next and previous occurence:
Pressing n after a forward search positions the cursor on the next occurence, forwards.
Pressing N after a forward search positions the cursor on the next occurence, backwards.
Pressing n after a backward search positions the cursor on the next occurence, backwards.
Pressing N after a backward search positions the cursor on the next occurence, forwards.
