This is because it's tagged as 'National Gallery / National Portrait Gallery'.
If they share the same physical building, there isn't an obvious way to tag it
with two separate names, so putting a slash may be the least bad option.

Semicolon is also used, as in 'Palace of Westminster; Houses of Parliament;
House of Commons; House of Lords'.  And a semicolon is used by some mapping
tools to join together names when two objects are merged.

So I suggest the namefinder should split names at slash and at semicolon, and
search each part separately.

I've added alt_name tags to this object, so after a database update it should
work.

Might be caused by the map having both an area and a node for the attraction.
I have tidied this to just the area.

This is semicolons getting into the tagging again; I've changed it to just
'museum' since that is more specific than 'attraction'.  The two separate
results look like a namefinder bug (you had other examples).

There used to be separate tagging for the building and a node in the centre
of the building, which could explain one of the duplicate results.  I've
tidied that up.

>* National Portrait Gallery
>  - No results found

See discussion of slashes above.
