Ryan McKinley updated SOLR-139:
-------------------------------
Attachment: SOLR-139-ModifyInputDocuments.patch
implementing modifiable documents in UpdateRequestProcessor.
This adds two example docs:
modify1.xml and modify2.xml
<add mode="OVERWRITE,price:INCREMENT,cat:DISTINCT">
<doc>
<field name="id">CSC</field>
<field name="name">Campbell's Soup Can</field>
<field name="manu">Andy Warhol</field>
<field name="price">23.00</field>
<field name="popularity">100</field>
<field name="cat">category1</field>
</doc>
</add>
will increment the price by 23 each time it is run.
> Support updateable/modifiable documents

> It would be nice to be able to update some fields on a document without
> having to insert the entire document.
> Given the way lucene is structured, (for now) one can only modify stored
> fields.
> While we are at it, we can support incrementing an existing value - I think
> this only makes sense for numbers.
> for background, see:
