Subject Re: Subclassing DIH

yeah, i remember that thread -- it really seems like a driver issue, but 
understandable that "fixing hte driver" is probably more out of scope then 
"working arround in solr"

: I never did find a "good" solution to that bug however I did come up with a
: workaround. I noticed if I removed my deletedPkQuery then the delta-import
: would work as expected. Obviously I still have the need to delete items out
: of the index during indexing so I wanted to subclass the DataImportHandler
: to first update all documents then I would delete all the documents that my
: deletedPkQuery would have deleted.

i'm not a DIH expert, but have you considered the possibility of having 
distinct "entities" declared in your config, that both refer to the same 
logical entity -- one that you use fo hte delta importing, and one that 
you use for hte deletedPkQuery ?

I'm not sure if it would work, but based on another recent thread i saw, i 
think it might... any event, subclassing the entire DataImportHandler definitley seems 
like overkill for what you are trying to achieve -- we just need ot get 
some of the DIH experts to chime in here.
