+  body: |-
+    Removing this flag will enable skippers automatically on keyword, ip,
+    boolean,     date and numeric fields that have index=false and
+    doc_values=true.  In addition,  some fields in time_series and logsdb
+    modes will default to using doc values  skippers in place of points or
+    terms indexes.
