Hi Hao,
Riak's search AAE should eventually re-index your data. However, by default
AAE trees are rebuilt only once a week, and then only one tree is rebuilt
per hour on each node. It is possible to speed this up, though.
On one node, run 'riak attach'. Then, at the Erlang console run
riak_core_util:rpc_every_member_ann(application, set_env, [riak_kv,
anti_entropy_build_limit, {4, 3600000}], 60).
riak_core_util:rpc_every_member_ann(application, set_env, [riak_kv,
anti_entropy_concurrency, 4], 60).
riak_core_util:rpc_every_member_ann(application, set_env, [yokozuna,
anti_entropy_build_limit, {4, 3600000}], 60).
riak_core_util:rpc_every_member_ann(application, set_env, [yokozuna,
anti_entropy_concurrency, 4], 60).
The above will allow concurrent rebuilding of up to 4 trees per node per
hour. Be careful not to increase this too much on production systems. To
force expiration of the search AAE trees you can then run in the Erlang
console
riak_core_util:rpc_every_member_ann(yz_entropy_mgr, expire_trees, [], 60).
Hope this helps.
Regards,
Magnus
