.B index_intlen <integer>
Specify the key length for ordered integer indices. The most significant
-bytes of the binary integer will be used for index keys. The minimum
-value is 4, which provides exact indexing for 32 bit values.
-The default is 0, which disables the use of ordered indexing.
+bytes of the binary integer will be used for index keys. The default
+value is 4, which provides exact indexing for 31 bit values.
+A floating point representation is used to index too large values.
.TP
.B index_substr_if_minlen <integer>
Specify the minimum length for subinitial and subfinal indices. An
