Comment (by r-a-y):

 > A couple thoughts about how the proposed API syntax looks. Some of this
 is in contradiction to my initial thoughts yesterday, so bear with me :)

 I kinda like the current syntax as it's easy to write scopes for.  We also
 have to keep in mind that whatever syntax we decide will be used by plugin
 authors.

 ----

 {{{
 (
   ( item_id = 5 )
   AND
   ( component = 'blogs' OR type = 'activity_update' )
 )
 OR
 (
   ( component = 'groups' )
   AND
   ( item_id = 6 )
 )
 }}}

 This is probably the worse example for endorsing nested relation queries
 ;)  With that being said, here's how to translate that example into a
 `BP_Activity_Query` in the latest patch:


 {{{
 $activity = new BP_Activity_Query( array(
         'relation' => 'OR',

         // nested relation query
         array(
                 //'relation' => 'AND', // this can be omitted as the
 default relation is 'AND'
                 'item_id' => array( 5 ),
                 array(
                         'component' => 'blogs',
                         'type'      => 'activity_update',
                         'relation'  => 'OR',
                 ),
         ),

         // groups
         array(
             'component' => array( 'groups' ),
             'item_id'   => array( 6 ),
         )
 ) );
 }}}

 ----

 > There's currently no way to do negative filters. If I want to get all
 activity from components *other than* 'groups', there should be a way to
 do that.

 Updated patch supports this.  Here's an example:

 {{{
 $activity = new BP_Activity_Query( array(
         array(
                 'compare'   => 'NOT IN',
                 'component' => 'groups',
         )
 ) );
 }}}

 ----

 What are some other `'compare'` types we want to support?  I still have to
 do some further tweaking, but what do you think about diverging from the
 `WP_Meta_Query` syntax?
