Hello. I have imported North America from pbf file and all TIGER data 2012 for house numbers in the US.

When I do simple query like "q=17th" on my instance, I get results immedietely.

But when I do query for house number like "1250 14th Street" search hangs for many minutes, with running process: "postgres: nominatim nominatim_na [local] SELECT".

My slow query exactly looks like that:


My settings:

13GB RAM on the machine


shared_buffers =4GB
work_mem = 320MB
maintenance work mem = 256MB
effective cache size = 6GB

What could be the reason?

This sounds like the indexes on the TIGER house number table are not properly used. Make sure that the location_property_tiger has its two indexes, one on place_id and one on parent_place_id/housenumber. If the indexes are there, it normally helps to run an ANALYSE on the table.
