While this in some sense is true. The method might be the most general
but *our* algorithm is not the most general purpose search algorithm.
For instance, lucene can do fuzzy and proximity (within verses) which
we aren't close to being able to do. It can also do simpler things like
NOT, wildcards and metadata; and this within the one query. And it does
Searching is the most criticised feature of MacSword (using our current
method) the most common critisisms are the speed and the strange
syntax, or double wildcard searching. eg. god finding Gudgodah
Using lucene has given MacSword one of the best search bible engines
around. Although some day I might out-grow lucene, it has given me a
much much more powerful, fast and general search engine than our
current theoretically "general" engine.
Having said all that, nothing I've done has affected the sword library.
I link to the lucene jar straight from MacSword and use my own code to
do all the searching.
Hope this is persuasive. :)
