Dear All
I'm trying out the text search feature of Fuseki and am obviously
missing something.
A. Download Fuseki 1.0.0-SNAPSHOT
B. Unzip
C. cd into directory
D. ./fuseki-server --desc=config-tdb-text.ttl
--desc != --conf
--desc mount one dataset at a place named on the command line.
There can be only one dataset in the file (ditto arq.sparql --desc ....).
e.g.
./fuseki-server --desc=config-tdb-text.ttl --update /ds
--conf is a configuration file. It's walked to find the datasets in the
right order.

BOOM.

As far as I can see, this is becuse there are two datasets in the assembly
file and Fuseki wants a unique one. (I can't see a way of saying "use THAT
one".)
The obvious experiment of removing the non-text dataset from the assembly
produces (unsurprisingly) a different error: since the non-text dataset
(the object of the text datasets :dataset property) doesn't have a suitable
(sub)type(of ja:Model), the assembler complains.
What is it that I haven't realised I should be doing?
