> If we want to find the index of any input based on hashing trick then it is possible in https://spark.apache.org/docs/2.2.0/api/scala/index.html#org.apache.spark.mllib.feature.HashingTF but not in https://spark.apache.org/docs/2.2.0/api/scala/index.html#org.apache.spark.ml.feature.HashingTF.
> Should allow that for feature parity
