This is as simple as building a TRIE out of incoming words and storing the start index at the leafs.

Because q/s is about efficient DS. Trie is most efficient in handling dictionary than a hash table

@koustav.adorable why not maintain a hash table with value set to list of indexes? scan will take O(N), search is O(1)

it should use suffix array or suffix tree to solve the problem.

This problem is the same as string match. Can be solved using kmp algorithm. Complexity will be O(m+n) where m is the length of text and n is the length of given word. space complexity will be only O(n) for the pattern/word vector.
