I found a solution! man comm
Using previous example,
file1, one two three red
file2, four five
file3, red blue yellow
file4, blue one
- for each "word", create a file (with the same name), and its content
will be sorted list of filenames where "word" came from. So,
one -- file1 file4
red -- file1 file3
...
- to find cross reference of "one" and "red", do
comm -1 -2 red one
