Or maybe because it cached the search index to disk, like most helpfiles.

This is what I'm currently researching for CHM. (merged CHMs/.chw files)
While currently it is fast enough, performancewise, "nice" results probably
need to mine more info.

I'd go shopping by the OS/2 centric compilers like sybil and vpascal. But
fat chance that they used some OS/2 tool for it that isn't ported.
