> When doing prefix searching, you need to hang on to the original term othewise you'll miss many matches you should be making.
> Data: ABC-12345
> WordDelimiterFitler may change this into
> ABC 12345 ABC12345
> A user may enter a search such as
> ABC\-123*
> Which will fail to find a match given the above scenario.
> The attached patch will allow the use of the "preserveOriginal" option to WordDelimiterFilter and will analyse as
> ABC 12345 ABC12345 ABC-12345
> in which case we will get a postive match.
