Question

Is there a way to increment a numeric field in solr that is indexed but not stored?

I.e. I have

<add>
    <doc>
        <field name="n">10</field>
    </doc>
</add>

And the schema is something like:

<field name="n" indexed="true" stored="false" type="tint" />

And I want to do an update on n where for example i increment the current value by some value m.

The only thing I can think of is to make the value both stored and indexed, and then when I want to update the value I have to query solr to get the existing value then call the update endpoint to write out the new value. Or is there an easier way?

SOLR-139 was recently committed that will allow adding etc, but:

• fields must be stored
• Fix Version is not set but I guess is only on trunk
