[Frontend] Add a grouping to the 'key' of the search-bar

The filtered search does not supporting left side (keys) grouping as we need.

we need to:

• Add to filtered-search component the ability to define grouping by keys titles), not just in the value as today.

• Update the Storybook accordingly.

(I'm working on a POC to see if this option is implementable or if we need to think differently.)
