The current behaviour of the 'enter' key when focus is within the EditText of SearchView is to attempt to render a protein with PDB ID of the EditText's current content. For example, if a user enters 'cro dimer' into the EditText and hits 'enter' on the soft keyboard, Palantir will attempt to render the protein with the PDB ID 'cro dimer'---which clearly does not exist. This behaviour is unintuitive.
Instead, the 'enter' should execute a text search, then render the first result of said text search. Palantir should only take the search query as PDB ID when it is in the form of a PDB ID. That is,
If search query matches regex \d[A-Za-z]{3}, then try to render the protein with PDB ID equal the search query.
Otherwise, do a text search. If there are results, render the first hit. Otherwise, show an error in the status line.
