Nominatim, which I worked with at MapQuest Open when it launched, is a great geocoder for purely OSM data. We built Pelias (<a href="https:&#x2F;&#x2F;github.com&#x2F;pelias" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;pelias</a>) at Mapzen because Nominatim is not built to handle autocomplete. We also wanted to start with a fulltext search engine -- Elasticsearch in this case -- instead of Postgres with search logic on top of it. We also wanted to search other open datasets like the fast-growing OpenAddresses.<p>We host Pelias at Mapzen and you can check out the autocomplete as well as fulltext search here: <a href="https:&#x2F;&#x2F;mapzen.com&#x2F;projects&#x2F;search" rel="nofollow">https:&#x2F;&#x2F;mapzen.com&#x2F;projects&#x2F;search</a>
