vim Get :help (using Vim's built-in manual) Searching the manual
Example
:help [subject] attempts to find the "best" match for the argument you supply. The argument "can include wildcards like *, ? and [a-z] (any letter).
You can additionally use Vim's command-line completion with CTRL+D:
:help spli<Ctrl-D> will display a list of help topics matching the pattern spli, including split(), and :split.
To search for Ctrl-based commands, like Ctrl-V, type:
:help ^V with a literal caret character, or even more specifically,
:help i_^V to get help on Ctrl-V in insert mode.
As you see, vim has a nomenclature for its help topics. For instance, options are quoted (see :h 'sw'), commands start with a colon (see :h :split), functions end with empty brackets (see :h split()), insert mode mappings start with i_, command mode mappings start with c_, and so on, except normal mode mappings that have no prefix.
