Sets the character-matching mode for attribute comparison searches,
e.g. equals, less-than, order-by, IN. This controls aspects
like case-sensitivity, ignoring accents, etc. See Text Search
Mode (here) for details on what the setting
values mean. The default is Exact. Note that searches on
Enum fields are unaffected by this setting, as the
Enum type is defined to be case-insensitive.
Note: Changing the Attribute Compare Mode setting will
cause Extra Indexes (if any) to be rebuilt. This may take a few
minutes on large profiles, and may prevent walks from proceeding until
the indexes finish.
