: Huh, does !term in 4.0 mean the same thing as !field in 1.4? What you
: describe as !term in 4.0 dev is what I understand as !field in 1.4 doing.
There is a subtle distinction between {!field}, {!raw}, and {!term} which
i attempted to explain on slides 26 and 43 in this presentation...

(you can use the HTML controls or "print preview" to view the notes i had
when giving it)
The nutshell explanation...
when building filter queries from facet constraint values:
* {!field} works in a lot of situations, but if you are using an analyzer
on your facet field, there are some edge cases were it won't do what you
expect.
* {!raw} is truely raw terms, which works in almost all cases where you
are likely using facet.field -- but it's too raw for some field
types that use binary term values (like Trie)
* {!term} does exactly what you would expect/want in all cases when your
input is a facet constraint. it builts a term query from the human
readable string representation (even if the internal representation is
binary)
