I searched for the article "gound plane" on English Wikipedia. Note the misspelling. The search page says, "Did you mean: gould plant". However, clicking on "gound plane" at the end of the phrase results in the dropdown suggestion "Ground plane". I suggest making the better search suggestion appear also, or instead of, the "gould plant" suggestion.
The impression I get from this situation is that there is a different algorithm that produces the "gould plant" suggestion from the "ground plane" suggestion, so perhaps one suggestion algorithm should be replaced with the other.
