People are working on "field update", but that feature is not currently
available in a release of Solr.
You can read about the current status of that work here:
https://issues.apache.org/jira/browse/SOLR-139
It may or may not be usable for you today - in trunk.
But if field update is important to you and you don't want to use that
patch, you could implement a custom update processor that performed the
read/increment/write sequence as you need it. That would require all of you
fields to be stored, which is probably what you have if you are doing the
update remotely. Take a look at SOLR-139 first.

Subject: Indexing to add to a field, not replace
Hello,
Is it possible to perform an index commit that Solr would add the incoming
value to an existing fields' value?
I have for example:
<fields>
<field name="book_title" type="string" index="true" stored="true"
required="true" />
<field name="count" type="int" index="true" stored="true"
required="true" />
</fields>
Currently, I am doing a search to retrieve the current value of "count",
then doing the addition on my processing server then committing the new
"count" value. Is it possible to use a copyField or a custom field type
that would perform this addition for me so I can skip the search query?
Thanks in advance for your time!
- Mark
