Ronan KERDUDOU commented on LUCENE-1100:
----------------------------------------

when having in a text : "5.3.2-bl=C3=A0hblah" this is detected as a NUM... =
and "2.45" is detected as a HOST...
I think when there's a mix of alpha and num the '-' should be considered as=
 a whitespace... and that a {NUMERIC}[.,]{NUMERIC} must be a NUM and not a =
HOST.
also something like "image.gif" shouldn't be a HOST...
I know it's very difficult to make this flex file perfect.

"TEST" and "2010" are ALPHANUM, I would prefer to distinguish a ALPHA and a=
 NUMERIC instead of ALPHANUM...
"2,5" and "9-juin-2009" are NUM, i would prefer to distinguish NUM_DECIMAL =
and NUM_LIKE

i think sometimes we would have a better index if we could have 2 tokens wi=
th the same part of the file.
for exemple : "5.3.2-bl=C3=A0hblah" would make a token but another token "b=
l=C3=A0hblah" should be added.
maybe we should do it in the StandardTokenizer to complete the power of the=
 flex file ?

 See https://issues.apache.org/jira/browse/LUCENE-1068.  There may be other=
 things like this that are marked as incorrectly as well.
