Andy
Many thanks for speedy and accurate reply. Good idea to back-port the
error checking from Fuseki 2.
That works now with
<#service_spatial_tdb> rdf:type fuseki:Service ;
rdfs:label "TDB/spatial service" ;
fuseki:name "text" ;
...etc...
<#service_text_tdb> rdf:type fuseki:Service ;
rdfs:label "TDB/text service" ;
fuseki:name "spatial" ;
...etc...
Couple of final things.
This seems to work only if you POST to the correct endpoint. E.g. if I
post updates of geo:lat/long triples to the "update/text" endpoint they
don't get indexed, but GETting a query with spatial:nearby and
text:query works in either text or spatial. Is this correct behaviour,
or am I still doing something wrong?
Can you put an example of this in the docs/release. There are text or
spatial examples of configs, but not one with both. Took a long time to
find that one in the mail archive and that has the same mistake as I
made. (not surprising as I copied it :-) )

^^ is wrong
Many thanks again
