NotFoundException about hdt-java HOT 3 CLOSED

Hi Sebastian,

The exception means that one of the terms in the search does not exist in the dictionary.

org.rdfhdt.hdt.exceptions.NotFoundException: String not found in dictionary

In fact, if all terms exist, the result of the query is empty as you mentioned.

But we can change it to return a null iterator if one of the terms doesn't exist (as in hdt-cpp). Please vote with 👍 if you agree to return a null iterator.

Ok, I see that HDT is special in this respect compared to a database. However, I am not aware of any data structure that throws an exception if something is not found in the database. I can't judge whether this is valuable information that something that is not in the dictionary is queried. I would expect it to just return an empty iterator, if no result is found.

You are right, and essentially it makes no sense to have two different approaches in C++ and Java.

I have added an empty iterator in d26a0af

Now you have the expected empty iterator if a term is not found.
