.B olcIndexHash64: { on | off }
Use a 64 bit hash for indexing. The default is to use 32 bit hashes.
These hashes are used for equality and substring indexing. The 64 bit
version may be needed to avoid index collisions when the number of
indexed values exceeds ~64 million. (Note that substring indexing
generates multiple index values per actual attribute value.)
Indices generated with 32 bit hashes are incompatible with the 64 bit
version, and vice versa. Any existing databases must be fully reloaded
when changing this setting. This directive is only supported on 64 bit CPUs.

.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
