The percentage of killed documents in a single generation for it to be considered for re-indexing.
Can be set in: collection.cfg
The percentage of killed documents required in a generation before it will automatically re-index. Automatic reindexing also requires the minimum document threshold to be reached. This option is useful in stopping large generations with mostly killed documents from existing.
By default, Push will re-index any generation when 50% of the documents have been killed and the minimum document threshold has been reached.
