Here is a result of your thoughts.
function! Searchfile(file, pattern, ...)
if exists("a:1")
let matchlimit = a:1
else
let matchlimit = 1
endif
let list = []
let matches = 0
for line in readfile(a:file)
if match(line, a:pattern) != -1
call add(list, line)
let matches += 1
if matches == matchlimit
break
endif
endif
endfor
return list
endfunction
