+. : Secondary Hash Tables
+LSDB can also have one or more number of secondary hash tables.  These
+hash tables are mainly used to hint lsdb-hash-table to gather
+additional relationship information between record name and entries.
+For example, lsdb-address-cache is a kind of secondary hash table
+which holds the mapping of mail addresses to record names.
+
+The variable lsdb-secondary-hash-tables holds a list where each
+element is corresponding to the name of global variable such as
+lsdb-address-cache.  When the primary hash table is loaded or saved,
+the secondary hash tables will be handled automatically.
