keyword database is not working anymore as expected

[rombaum]

I did a query via the TSS autocomplete widget and I used the parameter database with the value skosmos. I entered milk into the search input field. I would expect as a response only one concept from Agrovoc but i got multiple back. I would guess that the reason for this could be the added local indexer. It was working as describe at the end of July. The similar behavior appears when I use ols or ontoportal as values of database.
