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