We need to create an autocomplete functionality so that as the user is typing suggestions are shown from the backend elasticsearch indices.
Which is the better option for indiex that has 10 million plus records and the fields that need to be searched for the suggestions are between 100 - 1000 characters long:
1- The Completion Suggester or
2- Search as you type field
We have been told that for large Indices, the completion suggester is not a good choice due to it using in memory to store the data hence slowing and even crashing the cluster.
