Then I wrote this little code :

function! s:getPatternCount(begL,endL,pattern)
let netrkC = 0
if copy(a:begL) < copy(a:endL)
for lnum in range(copy(a:begL), copy(a:endL))
if stridx(copy(getline(lnum)), copy(a:pattern)) == 0
let netrkC += 1
endif
endfo
endif
return netrkC
endfu
let networkCount = s:getPatternCount(copy(s:getPreviousLineBlock()), v:beval_lnum, 'NETWORK')
