Erick Erickson resolved SOLR-7572.
----------------------------------
Resolution: Cannot Reproduce
Closing a few tickets out on the theory that improvements since 4.10 have taken
care of this situation. We're seeing very high indexing rates in numbers of
clients with recent Solr releases not exhibit this problem. We can open new
JIRAs if we see this again.
> hard commits with waitSearcher=true occasionally returns without waiting
> leading to inconsistent views of the index.

> Key: SOLR-7572
> URL: https://issues.apache.org/jira/browse/SOLR-7572
> Project: Solr
> Issue Type: Bug
> Affects Versions: 4.10.3
> Reporter: Erick Erickson
> Assignee: Erick Erickson
>
> Another observed behavior while working with a customer, possibly related to
> SOLR-7571. Again, assigning to myself but feel free to take it.
> Issuing a commit (openSearcher=true) sometimes returns immediately and does
> not actually work as expected.
> Here's the process.
> > Index a bunch of documents with timestamp=T1. Some time later update many
> > (but not all) of those documents with a more recent timestamp=T2.
> > issue a hard commit waitSearcher=true
> > Issue a query ...fq=timestamp:[* TO T1]
> The return count includes many (all?) records with timestamp=T1. Simply
> waiting for "a while" and re-issuing the query will eventually return the
> correct number of docs.
> autocommits are disabled here, i.e. hard commits are happening with
> openSearcher=false and soft commits are disabled in solrconfig.xml. There are
> no other clients sending commit messages.
> Of course this is not reproducible at will and whether it's related to the
> client firehosing updates to Solr I don't know yet.
> To pursue this I'm hoping to set up a "firehose" test scenario and see how
> many of these I can reproduce.
