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?
Could you try the latest version please?
IIRC There were fixes for the text index in this area.
I'm not sure the state of the spatial code as to whether the same was
needed or applied.

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

Hi Mark,
You have different two datasets of the same name ("ds"). I doubt any
requests are going to the first one each time. The first declaration
got replaced by the second. I'll make that an error - it is in Fuseki2.

Hi Jena team.
I'm trying to get both the text and spatial indexes to work on my TDB
store using jena 1.1.0 (and 1.1.1). I can get one or the other to work,
but not both at the same time. Can you help?
I based by config with the example here:
http://mail-archives.apache.org/mod_mbox/jena-users/201402.mbox/%3cade748d9f3894b85bef1583f6e328...@by2pr04mb613.namprd04.prod.outlook.com%3E
Which _seemed_ to work fine, but I realised that the text index wasn't
being updated. Queries with spatial predicates worked fine, e.g.
PREFIX iotic: <http://purl.org/net/iotic-labs#>
PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#>
PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#>
PREFIX spatial:<http://jena.apache.org/spatial#>
PREFIX geo:<http://www.w3.org/2003/01/geo/wgs84_pos#>
SELECT ?ent ?lat ?long
WHERE
{
?ent rdf:type iotic:Entity .
?ent geo:lat ?lat .?ent geo:long ?long . ?ent spatial:nearby(52.2474
0.7183 5.0 'km')
}
_but_ queries with text predicates did not work.
PREFIX text: <http://jena.apache.org/text#>
PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#>
SELECT ?s
{ ?s text:query (rdfs:label 'weather' 10) ;
rdfs:label ?label
}
Here's the weird thing. If I change the order of the services in this
bit of my config file, delete the data directories and restart fuseki,
then the spatial queries stop working and the text queries do work.
# Spatial queries work, text do not.
fuseki:services (
<#service_text_tdb>
<#service_spatial_tdb>
)
# Text queries work, spatial do not.
fuseki:services (
<#service_spatial_tdb>
<#service_text_tdb>
)
