> First of all I apologize for possible duplicate posts. I sent it to the
> mailing list, it disappeared from the "draft box" but didn't show up again in
> the "sent box" either. So I try to publish it here before I lost it from my
> clipboard. :D
> Here is the copy of the mail:
> Hi Andy,
> I am sorry for such a late response. We were busy on another project during
> this period. Now I try to explain how I reproduce the error step by step.
> So the problem is there is something wrong in the search indexing for
> in-memory datasets.
> Here is the configuration file I used, it should be basic enough: a server
> description, a service description and an index engine associating to the
> dataset to index "rdfs:label".

> In 2.0.0:
> If I load some triples not containing "rdfs:label", everything works
> properly. However in this case the index engine is not working; then as long
> as I add one triple for "rdfs:label" into the file I am loading to Fuseki,
> error emerges:

> I remember that a few months ago when 2.0.0 was released for the first time,
> I discovered this issue and reported to you. But at that time I didn't
> realize that the root reason was because of indexing. In a later snapshot you
> fix it, but my test wasn't proper so I thought the problem is solved and gave
> you a wrong feedback. My sincere apologizes.
> In 2.0.1 SNAPSHOT:
> The latest snapshot contains the patch I mentioned above so they can be
> successfully loaded. However they are not indexed at all. Queries with
> keyword search do not return any result.
> Following your advice, I tested loading and query from both Web UI and
> s-post/s-query tools, unfortunately (or fortunately?) the consequences are
> the same.
> TDB:
> Meanwhile, a similar experiment on Fuseki with TDB in 2.0.0 and 2.0.1
> SNAPSHOT is also performed, they both works properly. Loadings are successful
> and queries returns search results. The only difference is in the
> configuration file the in-memory dataset is replaced with TDB.
