Queries with FILTER depend on whether there is a . before

[hannahbast]

The following query works on Wikipedia+FreebaseEasy:

SELECT ?x WHERE {
  ?x <is-a> <Astronaut> .
  FILTER (?x <= <Akihiko_Hoshide>)
}
ORDER BY ASC(?x)

Without the DOT (.) before FILTER, all results are shown (as if there was no FILTER).

PS: The query does NOT work with quotes around the enity names. However, it does work when the entity name does not exist, for example:

SELECT ?x WHERE {
  ?x <is-a> <Astronaut> .
  FILTER (?x >= <Neil)
}
ORDER BY ASC(?x)

I think this is actually an incarnation of Issue #21. The SPARQL standard demands the . but our parser is too crazy and accepts all kinds of weird inputs without useful warnings.

This too should be solved by #258

This was fixed by merging #258
