How to convert numeric words to numbers while importing data to ElasticSearch?
I am using ElasticSearch 5.6, and my data often involves numeric strings containing ordinal or cardinal numbers as "fifth", or "forty-one" or "one hundred and twenty two". I want an analyzer whose token filter will stem these numeric word forms into its more basic numeric form, like,
"fifth" ==> 5
"forty-one" ==> 41
"one hundred and twenty two" ==> 122
Doing this via synonyms would be very cumbersome and I am not able to do it correctly using Pattern replace. During both input and search process, data may contain all forms of numeric words, like 5 / 5th / Five / Fifth.
Any help here would be appreciated!

This sounds like a job for a custom analysis plugin. I am not aware of one that does this, however.
