Nice tip I found while searching interactively (C-s).

If you want to see all the occurences of what you’re just searching for, press M-s o and you will see new buffer listing all the desired occurences. Moreover, you may extend searching convieniently by selecting next words with C-w.

This flow C-s C-w C-w M-s o selects 2 words starting at current cursor position and lists all their occurences in current buffer.

Obviously, the greatest way to simplify all above is hidden under the ‘anything’ hood. Try anything-occur and hear your jaw dropping :)
