In the section "near real time search" of the book "Elasticsearch: The Definitive Guide":
The Figure 20 depicts how in-memory buffer contents been re-freshed into segment in filesystem cache.
The the figure, the commit point includes three GREEN segment, but not include that gray segment in filesystem cache.
My understanding is, the commit point in this situation should include the gray segment as well, since the commit point lists all known segments which are searchable and the gray segment in filesystem cache is searchable now.
Am I right?
