updating solr document using a query?

In the solr documentation, there are options to delete documents using a query, something like the following:

<delete><query>*:*</query></delete>
<delete><query>id:298253</query>
<query>entitytype:BlogEntry</query></delete>

However, I could not find any references about updating documents based on a query. Is this possible with updates in solr? Basically I would like to update the values of all the documents that match a query.

Something like update prop1=val1, prop2=val2 where ( prop3 < val3 and prop4=val4 )

Thanks,
-Vineel

Keep in mind that for partially updating documents in Solr, they need to be stored. Which increases the index size. Check this for some background

The ability to update documents is being added to the Solr 4.0 release, which just went into Beta this week. I am not sure if there will be the ability to update documents based on a query, but you could ask in the Solr Users List. Unfortunately, I have not had a chance to explore the 4.0 version yet to see how atomic updates work.
