Maybe I am out of sync but I do not really understand the purpose of these.
Does this mean we write:
query = (dc.titleAllTheseWords="a b c")?

My logic tells me that this is mixing index type with default operator,
resulting in an explosion of pseudo index types all translating to word. I
would prefer one of the following:

query = ((titleWord="a") and (titleWord="b") and (titleWord="c"))
query = (titleWord="a" and "b" and "c")

Whatever dc defined having a (virtual pseudo ) index dc.titleAnyOfTheseWords
is mixing user interface and index definition. It also makes things fuzzy,
for instance what does in this case "all-of-these-words mean". (It gets more
funny if you use Chinese examples)
