I have document indexed with TITLE **have some happy meal**. When I search **have some** , I am able to get proper highlights.  
**_have_ _some_ happy meal**

As i type more **have some ha** , the highlight results are not as expected.  
**_ha_ve _some_ _ha_ppy meal**

The **have** word gets partially highlighted.

I would expect it to highlight the longest matching token, because with an ngrams with min size = 1, this gives me a highlight of 1 or more char while there should be another matching token of 4 or 5 chars (for example: **have** should also be highlighted along with **ha** being highlighted)
