Need to update a field without re-indexing in solr 3.6

[Thakur, Pramila]

Hi Everyone,

I am using Solr 3.6. I want to update a single filed value in the index without 
re-indexing. Is this possible?
I have google and came across partial update in solr 4.0 BETA.

Can I do do this with Solr 3.6?

Thanks,
