Description

Is your feature request related to a problem? Please describe. Modern search engines have a functionality called autocompletion. For example, when user types in "tan", the search engine suggest the word "tantivy"; when user types in "tantivy", the search engine suggest the phrase "tantivy search engine". For frontend, this is often seen as a drop down list below the search area.

Lucene has a module Lucene suggest which provides such functionality.

Describe the solution you'd like Implement a module which provides such functionality.
