Nearly every Sword application can build a fast index for searching.
Each has a different way of exposing that capability. That index, once
built, is blazingly fast. And this also exposes boolean search capabilities.
The reason that you are experiencing slow search is that you are using
an old search mechanism. It essentially has to parse the OSIS xml for
each verse to extract the text and then search the result. It does this
for every verse. If you do another search, it does it all over.
