Ronan KERDUDOU commented on LUCENE-1100:
----------------------------------------
when having in a text : "5.3.2-blàhblah" 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 with the same part
of the file.
for exemple : "5.3.2-blàhblah" would make a token but another token "blàhblah" should be
added.
maybe we should do it in the StandardTokenizer to complete the power of the flex file ?
