Right. As I mentioned on the original JIRA, the regex match is happening on
_terms_.
You are conflating the original input (the entire field) with the
individual terms that the
regex is applied to.
I suggest that you look at the admin/analysis page. There you'll see the
terms that are
indexed and you'll see that the regex simply cannot work since it assumes
that the
regex is applied to the entire input rather than the results of the
analysis chain.
I further suggest that you explore tokenization and how
individual terms are searched. The admin/analysis page is invaluable in this
endeavor.
The root cause of your confusion is that, given you're using
ClassicTokenizer,
you have a bunch of individual terms that are being searched, _not_ the
whole
input. So the regex is bound to fail since you're thinking in terms of the
entire
input rather than the result of your analysis chain, i.e. tokenization +
filters
as defined in schema.xml.
FWIW,
