setMaxBufferedDocs
Determines the minimal number of documents required before the buffered in-memory documents are flushed as a new Segment. Large values generally give faster indexing.
When this is set, the writer will flush every maxBufferedDocs added documents. Pass in IndexWriterConfig.DISABLE_AUTO_FLUSH to prevent triggering a flush due to number of buffered documents. Note that if flushing by RAM usage is also enabled, then the flush will be triggered by whichever comes first.
Disabled by default (writer flushes by RAM usage).
Takes effect immediately, but only the next time a document is added, updated or deleted.
