Is this a bug? An error in the collection or computation of the search results perhaps?
I did a search for a word that appears only in one entry. Search results correctly returned this entry but the percentage was listed as 0%. If I search for a word that appears in several entries, I again get the proper entries listed but percentages can be anywhere from 100% to some -nn%.
