>
> We can support EQ/PREFIX requests to CONTAINS indexes by tracking 
> "partiality" of the data stored in the OnDiskIndex and IndexMemtable, if we 
> know exactly if current match represents part of the term or it's original 
> form it would be trivial to support EQ/PREFIX since PREFIX is subset of 
> SUFFIX matches.
> Since we attach uint16 size to each term stored we can take advantage of sign 
> bit so size of the index is not impacted at all.
