How to achieve Pattern matching using custom dictionary in HANA Text Analytics

$

Hello Folks,

 

I was able to run the text analytics using custom dictionary ( with fixed strings and even with wild card searches ) . I have a question on how to achieve a pattern search

 

ex: how to search for a phone number in the data?

      (We know the pattern of the phone number like 10 digit number ; starting with +1 ; ) but how do we write this in Custom dictionary? I am sure we can achieve this using regular expressions but would like to know if there is a way to do the same using custom dictionary in HANA.

 

Appreciate your help on this

 

Regards,
