The call to remove probably removes the node from the index, nit the key from
the node. You need to remove then completely reminded the node, including the
other two keys.

Subject: [Neo4j] Numeric index update
Hi.
I have a problem with following test (perform it on an empty database).
First we add same node to the index with different keys and values. One of
them is numeric. After that - check that node may be found using these keys
and values. Then - update value for one of the keys and try to get node from
indexes. For text index node is not null, but for numeric index node is not
found, though the query is the same.
public class DBTest {
public static final String TEXT = "text";
public static final String NUMERIC = "numeric";
public static final String TEXT_1 = "text_1";
@Autowired GraphDatabaseService db;
@Test
public void updateIndex() throws Exception {
Transaction tx = db.beginTx();
try {
Node n = db.createNode();
getIndex().add(n, NUMERIC, new ValueContext(5).indexNumeric());
getIndex().add(n, TEXT, "text");
getIndex().add(n, TEXT_1, "text");
tx.success();
} catch (Exception e) {
tx.failure();
} finally {
tx.finish();
}
Node n = getIndex().query(QueryContext.numericRange(NUMERIC, 5, 5,
true, true)).getSingle();
assertTrue(n != null);
n = getIndex().get(TEXT_1, "text").getSingle();
assertNotNull(n);
tx = db.beginTx();
try {
// Following line may be commented, it's addition of node that
causes the problem
getIndex().remove(n, TEXT, "text");
getIndex().add(n, TEXT, "text 1");
tx.success();
} catch (Exception e) {
tx.failure();
} finally {
tx.finish();
}
n = getIndex().get(TEXT_1, "text").getSingle();
assertNotNull(n);
n = getIndex().query(QueryContext.numericRange(NUMERIC, 5, 5, true,
true)).getSingle();
// Test fails here
assertNotNull(n);
}
private Index<Node> getIndex() {
return db.index().forNodes("index");
}
}
