Search using keyword presented in excerpt

Hi,

If we search using the keywords presented in the excerpt of any post, then results are not showing(custom field values also).

Suppose i am having one main keyword in Excerpt so if i search using this keyword then that product(grid_products plugin) should display but it is not showing that product in search.

Can you please suggest me the solution.

Thanks.
Padma GV.
