Cscope is another choice also,
cscope provice more search types than ctags
cscope -Rbk to build the database first,
add following section to the ~/.vimrc, then can use the hotkey.
if has("cscope")
    " use both cscope and ctag for 'ctrl-]', ':ta', and 'vim -t'
    set cscopetag

    " check cscope for definition of a symbol before checking ctags: set
to 1
    " if you want the reverse search order.
    set csto=0
    " add any cscope database in current directory
    if filereadable("cscope.out")
    	""if $CSCOPE_DB != ""
           cs add cscope.out .
    " else add the database pointed to by environment variable
    elseif $CSCOPE_DB != ""
        cs add $CSCOPE_DB

    " show msg when any other cscope db added
    set cscopeverbose

    " To do the first type of search, hit 'CTRL-\', followed by one of
    " cscope search types above (s,g,c,t,e,f,i,d).  The result of your
    " search will be displayed in the current window.  You can use
    " go back to where you were before the search.
