Nominatim wildcards*

As far as I know Nominatim does not do partial or wildcard searches.

Technically I am sure it is feasible, although there may be some issues with parsing given that Nominatim is designed to work across multiple languages.

I suspect that such a feature has not been implemetned for two good reasons:

• Developer time & resources. Nominatim is developed by a small pool of people who undoubtedly have along list of things to sort out. Most of these things will be with what might be considered to be core functionality. Partial search is probably not in this core. Certainly fuzzy matching is not.
• Performance. Partial and wildcard searches are likely to impose an unsupportable load on the Nominatim server. Only some queries would be supported by indexes with the very real risk that a single query could deny the service to everyone else through requiring table scans of the base data.

In general I find the type of query you need to be met by the Nominatim using something like the following:
`

< amenity > near < town|place >

`

Nominatim has very limited partial search support. You'll find that searching for Sesame, North Lakes actually returns the expected object. (There are simply too many places named Sesame on this planet for an unrestricted search to work out.)

Searching for Sesame Lane, you will run into this bug. Once the bug is fixed you should get results for it, too, but don't expect miracles. SK53's answer as to why partial search works badly is spot-on.
