title: How to search not matching pattern in VIM
body: <p>Here is an excerpt of my <code>.py</code> file:</p>
  
  <pre><code>for i in range(1,nxs-2):
      for j in (1, nts-2):
          dg_cc(dg,sina,cosa,s,r2tanb,omega,L,n,m,xs[i],ts[k],pd)
          dot( dg,F,c1,transa=T )
          dot( c1, dg, ansK1, N, N, alpha=2., beta=1. )
          # linear buckling part
          g = g_cc(m,n,L,xs[i],ts[j],pd)
          Bg = fBg(Bg,cosa,s,L,m,n,xs[i],ts[i],pd)

  <p>I have to fix all the typos keeping only <code>ts[j]</code> and fixing those with <code>ts[i]</code> or <code>ts[n]</code>, for example.</p>
  
  <p>How do I build my searching pattern in order to get everywhere where <code>ts[something]</code> <code>something NOT equal j</code>?</p>
