IndexDictionary.Builder
The Uniform Split technique adds block keys in the dictionary. See
BlockReader
and TermBytes
for more info about block
key and minimal distinguishing prefix (MDP).
All block keys are added in strictly increasing order of the block file pointers,
this allows long encoding optimizations such as with PositiveIntOutputs
for FST
.
