Dear Leandro,
i have found out the reason for this malfunction and it is both a
feature and a bug (complex world).
Let me clarify how the semantic queries work when you require documents
as result.
The first thing happening after you execute the query is that all
entities matching the criteria are being retrieved.
This is the place of the short-circuit. Here we have applied a default
limit over the number of entities which are to be returned in order not
to over-flood result set. Since the modelling of location instances in
the knowledge base is extensive, simply - the adequate entities have not
succeeded to be among the result set. From there on the documents are
not appearing in the result set.
I agree it is a stupid behaviour. We have worked in the direction to
improve this and i expected it not to have these limitations. What we've
done is : we have introduced methods for getting entities or documents
with an additional parameter limiting the expected result sets. However,
this means that the methods without this additional parameter should
return an unlimited result set, obviously - not the case now.
I guess Ilian will check it a bit further on Monday.
The way to make it work is to narrow down the set of entities matching
your query. What i've done was:
adding a name restriction over X
seq.addNameRestriction("X",seq.COMPARE_STYLE_CONTAINS,"Earth");
which returns the indexed document(s).
After these clarifications, we will be happy to hear what you think will
be the best way these methods should function.
Thanks for the source code and the log, it really made it very easy for
me to reproduce it
have a nice weekend
