I have a need to find mastercard numbers with regular expression.
I’m using Query query = new RegexpQuery(new Term("body",
"5{1}<1-5>{1}<0-9>{14}"), RegExp.ALL) to search numbers in email’s body and
StandardAnalizer used for body indexing. So number like 5106792294698422 will
be indexed as it is and all mastercard numbers will be on search results, but
numbers like 5106 7922 9469 8422 will be indexed as 4 tokens 5106, 7922, 9469,
8422, simular for 5106-7922-9469-8422.
Any ideas how to find the sequence of numbers with spaces, dashes etc? Maybe
multiterm regexp search query?

Valentin Popov
