Geo sparql issues with Lucene

[ate47]

Current Behavior

Using our dataset, we noticed that some GeoSparql queries doesn't have the same behaviours with or without a Lucene Sail with a Lucene index.

Sometimes the results are empty with the Lucene index and not empty without it, sometimes not empty with the Lucene index and empty with it.

Expected Behavior

Same results whatever the configuration is.

Steps To Reproduce

Using this dataset: geo2.zip

private void printHead(TupleQueryResult res) {
	for (int i = 0; i < 5; i++) {
		if (!res.hasNext()) {
			return;
		}
		System.out.println(res.next());
	}
	if (!res.hasNext()) {
		return;
	}
	int more = 0;
	while (res.hasNext()) {
		more++;
		res.next();
	}
	System.out.println("... +" + more);
}

@Test
public void geoSparqlTest() throws IOException {
	// use or not Lucene
	boolean useLucene = true;

	NotifyingSail store = new MemoryStore();
	if (useLucene) {
		LuceneSail lc = new LuceneSail();

		lc.setParameter(LuceneSail.MAX_DOCUMENTS_KEY, "5000");
		lc.setEvaluationMode(TupleFunctionEvaluationMode.NATIVE);
		store = lc;
	}
	System.out.println("Lucene: " + useLucene);
	SailRepository repo = new SailRepository(store);

	try {
		Repositories.consume(repo, RepositoryConnection::clear);
