+** within the same xBestIndex call.  ^If the interface returns true
+** (non-zero), that means that the constraint is an IN operator
+** that can be processed all-at-once.  ^If the constraint is not an IN
+** operator or cannot be processed all-at-once, then the interface returns

+**
+** In some cases, however, it would be advantageous for the virtual

+**   sqlite3_vtab_in() with -1 in the third argument is a mechanism

+**   of the IN operator is even possible.
+**
+** <li><p>

+**   parameter (F) is non-negative, this interface is the mechanism by
+**   which the virtual table tells SQLite how it wants to process the
+**   IN operator.
+** </ol>
+**
+** ^The sqlite3_vtab_in(P,N,F) interface can be invoked multiple times
+** within the same xBestIndex method call.  ^For any given P,N pair,
+** the return value from sqlite3_vtab_in(P,N,F) will always be the same
+** within the same xBestIndex call.  ^If the interface returns true
+** (non-zero), that means that the constraint is an IN operator
+** that can be processed all-at-once.  ^If the constraint is not an IN
+** operator or cannot be processed all-at-once, then the interface returns
+** false.

+** ^(All-at-once processing of the IN operator is selected if both of the
