org.lemurproject.galago.core.parse.TagTokenizer will tokenize "17.1" into {"17"}, not {"17", "1"}. The problem is in method tokenAcronymProcessing, line 544
if (token.length() - s > 1) { // should change to token.length() - s > 0
String subtoken = token.substring(s);
addToken(subtoken, start + s, end);
}
token.length() - s > 1 will miss single-character tokens
to ship in 6/2014 release.
