Re: Using Lucene's payload in Solr

[Chris Hostetter <ho...@fucit.org>]

: Is it possible to have the copyField strip off the payload while it is
: copying since doing it in the analysis phrase is too late?  Or should I
: start looking into using UpdateProcessors as Chris had suggested?

"nope" and "yep"

I've had an idea in the back of my mind ofr a while now about adding more 
options ot the fieldTypes to specify how the *stored* values should be 
modified when indexing ... but there's nothing there to do that yet.  you 
have to make the modifications in an Updateprocessor (or in a response 
writer)
