As far as a search field is concerned, when we search an item  
eg: jewel , just after typing "j" in the field , it should provide all the 
results starting with "j" 

but here the auto listing of items are not working ,

in the above image you can see that when 'y' is typed it provides 3 

results but all those results provided are the already searched names. 

Only the already searched names are shown in the result , it doesn't show 

the complete products in the page starting with `y`

eg(below) : when a new item is searched , no related items are shown in the dropdown  [![enter image description here][2]][2]

I have indexed as well as removed the cache, Still the case is same.

Can anyone help me out to resolve this issue?
