   I have also ran into this on our patent search system. In our index the problem is exagerrated by the larger documents tending to be more frequently reindexed so the 20% deleted documents can translate to 40% of the overall index size!
   For my use case 5% would be a massive improvement.
   
   I ccan definitely imagine that for a system where indexing is light and infrequent 2% may make sense to ensure optimal perfomance/disk usage, without requiring the explicit use expungeDeletes. Having said that 5% is definitely low enough for my use case.
