It sounds like they have improved the processing of the data with regard to mathematical text. Topaz uses a technique very similar to that used in DJVU. You can read about how DJVU works in our wiki. To be more precise it is like IW44 which is a simplified subset of DJVU. I suspect they have improved the glyph location and sizing techniques to optimize the use of mathematical equations. The database itself would not need changing to accommodate this sort of improvement, however, the scanning processing would need to be better. Glad to hear about this improvement.
