Description
Insert one triple into a blaze instance with the text index enabled:
<:s> <:p> "foo" .
Then run the following query:
select ?o ?d
where {
service bds:search {
?o bds:search "foo" .
}
values (?d) {
(<:a>)
(<:b>)
(<:c>)
}
}
Results in:
Selection [ Bindings [o=foo,d=:a], Bindings [o=foo,d=:a], Bindings [o=foo,d=:a], Bindings [o=foo,d=:b], Bindings [o=foo,d=:b], Bindings [o=foo,d=:b], Bindings [o=foo,d=:c], Bindings [o=foo,d=:c], Bindings [o=foo,d=:c] ]
For some reason, two values gives you four results, three values gives you nine results, etc. We are getting a cross product.
