 /**
+ * A search request by default executes against the most recent visible data of the target indices,
+ * which is called point in time. Elasticsearch pit (point in time) is a lightweight view into the
+ * state of the data as it existed when initiated. In some cases, it’s preferred to perform multiple
+ * search requests using the same point in time. For example, if refreshes happen between
+ * `search_after` requests, then the results of those requests might not be consistent as changes happening
+ * between searches are only visible to the more recent point in time.
