If you are looking for a "old place name", it is found. Right.
If you are looking for a place in an "old place name", it is not found. Wrong, well can be improved.

See test case [https://wiki.openstreetmap.org/wiki/Nominatim/TestCases#FR Nantes, Loire-Infrieure].

That works as expected. Nominatim simply refuses to update the search index for every object in areas as large as the Loire-Atlantique. It would be too expensive. I've manually updated the Nantes relation now and you can see that it works: http://nominatim.openstreetmap.org/search.php?q=+Nantes%2C+Loire-Infrieure
All the other objects will sort themselves out with time.

Thanks lonvia, I was about to close the ticket as it was working ;-).
Could you update the Wiki so we have an idea of how long it takes to update the indexes, especially for big geometries? Or include the information is the statistics.

Or indicate a way like the /dirty on a tile url to force the computation of the indexes of a zone / an OSM object?

The indexes get updated gradually when the objects themselves are changed again. There is no way to predict when exactly that will happen. At the moment there also exists no mechanism for manually kicking the DB to update.
