[sword-devel] Module index funny results

[Troy A. Griffitts]

Will,
	Index has been messed up for some time.  It currently returns the index 
into the 'testament' (old or new).  The drivers have ot and nt data 
files and Index is used to compute the offset.  It's dumb.  I know.  It 
needs to change.  There is a NewIndex()  method that should soon be 
renamed to replace the current Index() method.  You should be able to 
call vk->Index(vk->NewIndex());

	Hmmm...  I'm sorry.  Now that I look at your code, I'm not sure what's 
up.  I would have though Mat.3.16 would have been an index much smaller 
than 24124.

	AH!!!  Sorry.  Now I see.  Yes!  SWModule::Index was added for a 
previous implementation of a search engine which was submitted a couple 
years back.  It was not accepted for a number of reasons, which included 
using external lexical parsing libraries and other things what were 
never cleaned up.  I thought he had the SWModule::Index thing working 
though.  I don't think anyone else uses it (obviously not if it's 
broken).  Traditionally, it's against our container/key_domain concept 
to force a container to return a hash number for each of it's entries, 
though this is, in all practical senses, doable because the driver has a 
fixed number of entries on the disk.  The safest way is to store the key 
value and use the key class to do the comparison.  I know it's not more 
efficient than a 'long', but it's safest and works and will still work, 
even if entries have been added to the module.

Sorry, Index() should be fixed or removed.
	-Troy.
