Hoss Man commented on SOLR-269:
-------------------------------

> Different Q on usage: is this where my document mutator stuff should go??? If 
> I want a transformation done on a field, regardless of 
> where the data is coming from (XML update handler, CSV update handler, future 
> REST update handler, etc), how should that be done? 
> Is there a single place I can register a plugin to do this, and is 
> UpdateRequestProcessor where you see it happening?

i believe that was acutally the initial intent of UpdateRequestProcesso, note 
the javadocs...

 * This is a good place for subclassed update handlers to process the document 
before it is 
 * indexed.  You may wish to add/remove fields or check if the requested user 
is allowed to 
 * update the given document...
 * 
 * Perhaps you continue adding an error message (without indexing the 
document)...
 * perhaps you throw an error and halt indexing (remove anything already 
indexed??)

> A simple UpdateRequestProcessor was added to a bloated SOLR-133 commit. 
> An UpdateRequestProcessor lets clients plug in logic after a document has 
> been parsed and before it has been 'updated' with the index.  This is a good 
> place to add custom logic for:
>  * transforming the document fields
>  * fine grained authorization (can user X updated document Y?)
>  * allow update, but not delete (by query?)
