I wonder if we should change that so that components of a compound
word are consistently stemmed the same way.


Something like this

SELECT to_tsvector('english', 'Boyer-Moore-Horspool');
                       to_tsvector
----------------------------------------------------------
 'boyer':2 'boyer-moore-horspool':1 'boyer-moore':1  'moore-horspool':1  'horspool':4 'moor':3
(1 row)
