[BUGFIX] Keep hyphens when lexing words for indexed_search

This change makes sure hyphens are kept as part of a word instead of
removing them. Removing them led to "casesensitive" instead of
"case-sensitive" being lexed and added to the index, which in turn led
to that occurrence not being found when searching for "case-sensitive".
