Hyphen not being ignored

[mdlynam]

Hi;

I thought that X1 saw hyphens as punctuation and ignored them. If that's the case, please help me understand why a search for 533863 and 5-33863 return different, non-overlapping results.

I thought that X1 saw hyphens as punctuation and ignored them.

I thought it treated hyphens as spaces.

If so 533863 and 5-33863 will return different, non-overlapping results.

5-33863 is the same as "5 33863" not "533863 ".
