Use of name:prefix on streets in Utah

[dknelson9876]

What did you search for?

I am trying to search for the University Guest House, which is located at 110 S Fort Douglas Blvd in Salt Lake City, Utah.

Empty search results here

What result did you get?

(I admit I have no knowledge of how Nominatim attempts to expand abbreviations)

Depending on how I abbreviated different parts of the name, I got different results:

• 110 Fort Douglas Boulevard found the correct node
• 110 S Fort Douglas Boulevard found segments of the road
• 110 South Fort Douglas Boulevard found no results

What result did you expect?

When the result in the right place and just named wrongly:

When the result missing completely:

I expect all three of these searches to find the same node that was linked above

Further details

Correct addresses in Utah will make use of name:prefix and name:full on the road. In this specific case, the length of Fort Douglas Blvd is tagged:

name=Fort Douglas Boulevard
name:prefix=South

And the University Guest House is tagged:

addr:housenumber=110
addr:street=South Fort Douglas Boulevard

As the 'South' part of the address is technically part of the street name, but rarely signed, and therefore doesn't belong in name.

I am even more confused by this, because when I tried search for something else nearby (a random dorm) with the address 80 South Connor Road, I get different results:

• 80 Connor Road finds the correct building
• 80 S Connor Road finds segments of the road
• 80 South Connor Road finds the correct building (different than above)

Despite the fact that this building and it's street follow the same tagging (name=Connor Road + name:prefix=South, and addr:housenumber=80 + addr:street=South Connor Road)
