Hi, 1. openSearcher (autoCommit) According to the Apache Solr reference, "autoCommit/openSearcher" is set to false by default.
https://cwiki.apache.org/confluence/display/solr/UpdateHandlers+in+SolrConfig But on Solr v4.8.1, if "openSearcher" is omitted from the autoCommit config, new searchers are opened and warmed post auto-commits. Is this behaviour intended or the wiki wrong? 2. openSearcher and other default commit settings From previous posts, I know it's not possible to disable commits completely in Solr config (without coding). But is there a way to configure the default settings of hard/explicit commits for the update handler? If not it makes sense to have a configuration mechanism. Currently, a simple commit call seems to be hard-wired with the following options: .. commit{,optimize=false,openSearcher=true,waitSearcher=true,expungeDeletes=false,softCommit=false,prepareCommit=false} There's no server-side option, e.g. to set "openSearcher=false" as default or "invariant" (cf. searchHandler) to prevent new searchers from opening. I found that at times it is necessary to have better server- or infrastructure-side controls for update/commits, especially in agile teams. Client/UI developers do not necessarily have complete Solr knowledge. Unintended commits from misbehaving client-side updates may be norm (e.g. 10 times per minute!).
