You probably are aware of this already, but I want to be sure.
positionIncrementGap is _only_ applied between the last term of one
multiValued entry and the first term of the next. So say I have a text
field and the input looks like:
<doc>
<field name="text">some stuff </field>
<field name="text">other words </field>
</doc>
and my positionIncrementGap is 100. The term positions are
some = 0
stuff = 1
other = 101
words = 102
The equivalent in SolrJ is doing a SolrInputDocument.addField() call twice.
I'm just wondering if you could get the behavior you need by some
clever usage of multiValued fields....
Best,
Erick
