Hi all,

I am applying the prefix query on list field and using highlight query to see the matched result but it is giving first five matches. But according to requirement i want last entries in best match as my use case is to suggest search from your recent searched strings. Please suggest.

Try change the `number_of_fragments` [setting](https://www.elastic.co/guide/en/elasticsearch/reference/6.3/search-request-highlighting.html#highlighting-settings)

But list count cannot be assumed, it is increasing day by day. Also, it is not good in performance also.

Unbounded growth of a document is not a good strategy.  
Indices are designed to scale but not individual docs.  
I suggest you either:

1. Cap the number of recent searches you keep in a user profile doc or
2. Have one doc per search saved then use `sort` in your query requests to get the last N
