SearchBeforeIndexSynchronizationJmsMasterSlaveIT#searchNewMembersBeforeSynchronizationOnMaster assumes that just because the synchronization interval is set very high, index work created on slaves or the master itself are not searchable on the master. This is not correct. The changes will no be visible on the laves due to the high sync time setting, but they are visible on the master. When they appear there depends on the JMS queue processing speed.
