Duplicates and missing rows.
I am getting duplicates and missing rows. The duplicates seem to arise when the a value has been edited in the references. I do not know why the row is missing.

An example of a duplicate with the below SPARQL is "wd:Q21076992 * En røv bag øret" and the missing one is "wd:Q21083886 * Beton - historier fra skurvognen" from. I am also getting duplicate elements, e.g., "Ove Dahl, Ove Dahl (politi)". This seems also to be related to editing the value.

Scratch pad
A scratch pad beside the query box would be really convenient for quickly storing queries. The pgAdmin tool for managing Postgresql databases has had this feature for years (http://www.pgadmin.org/docs/1.6/images/query.png). The main use case is when people are experimenting with queries, they often need a temporary place (ends up being a text file) to store and compare variations of a query. This feature is an effective and "low-tech" alternative to providing multiple tabs for running queries.

Exceptions and timeouts using wikidata query service
Hi there,

there might be a problem with the current wikidata query service.

I try to write a tool, which can answer questions with given answer candidates. To accomplish this I match the children of a parsed entity from the question and match the found candidates with the given.

One way which is realy fast and effective is using queries like these:

But currently I am receiving timeouts or exceptions
