OK, payloads are a bit of a mystery to me, so this may be way off
base.
But...
The ordering of your analysis chain is suspicious, the admin/analysis
page is a life-saver.
WordDelimiterFilterFactory is breaking up your input before it gets to
the payload filter I think, so your payload information is completely
disassociated with from your terms and treated as individual terms
all by themselves. At that point what you get
in your index *probably* has no payloads attached at all!
Use the admin/schema browser link to actually look at the data (or
just go straight to Luke) and I believe you'll see that your position
information is being treated just like any other token in the input stream.
There should be nothing about payloads that prevents normal
text query on the text part, although.
