Settings of zero turn that part of the automatic commit off. That's a way for people to have the setting in their config but not have the setting active. I think I may have found the off-by-one problem in the CommitTracker code. In the master branch, line 161 reads: if (docs == docsUpperBound + 1) { Based on how the source object for the "docs" variable is handled, I think it should probably be: if (docs >= docsUpperBound) { While what you have seen does look like a bug to me, and something that I think should be fixed, configuring values that low is generally a bad idea. Commits that open a new searcher require a fair amount of time and cpu/memory resources to complete -- even soft commits. They should not be configured to happen extremely frequently, which a single-digit maxDocs value will do. That is likely to cause overlapping commits, which can quickly become a major performance issue. Configuring only maxTime usually results in more predictable operation than maxDocs. Thanks, Shawn
