Subject Re: multiterm numbers regexp search
Date Mon, 15 Dec 2014 13:00:05 GMT
You probably don't want to use StandardAnalyzer: maybe try 
WhitespaceAnalyzer, but you'll need to enhance your regex a little to 
deal with  punctuation since WA may give you tokens like:

5106-7922-9469-8422.

"5106-7922-9469-8422"

etc

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.
