[Xapian-discuss] Search for negation

[Daniel Enright]

Hi,

What is the flag to enable this feature? I assume it is enabled with
-enable-FEATURE[=ARG]

Is there a complete list of available feature flags available?  As
./configure -help doesn't list them.

Has this particular feature made it into 1.0.8?
