This is not that easy as you'll have to combine street names with cities (+village+country+zipcode) names while the import ...
Also if you do it this way I would rather use a real search engine
like lucene or elasticsearch.

Peter.
An idea is to import roads shapefiles from geofabrik.de in spatialite and make a sqlite database.
>After that you can search database for street names.
>Resulted SQLite database contains also the path of a street (a collection of geopoints) so you can reverse make a reverse geocoding.
