Vinicius: No, fetching the document from the index, changing selected values and re-indexing probably won't work at all. The problem is that you only get _stored_ values back from Solr. So unless you've specified 'stored="true" ' for all your fields, you can't use the doc fetched from Solr to update a field.
The partial documents update that Jonatan references also requires that all the fields be stored. You're best bet is to go back to your system-of-record for the data and re-index the whole document.
