[PATCH] searchview: improve naming and simplify hash override

[PATCH] searchview: improve naming and simplify hash override

[Eric Wong]

`%over' could be confused for the overview SQLite DB
instance, so call it `%override', instead.  There's
also no need to write a loop to override a hash when
the language can do it for us.
