Search suggestion module fixes

[rokoso]

Search suggestion module:

1. Fix suggesting disabled products
2. After selecting a suggestion -> one has to click "Search" button which is unnecessary. Selecting a suggestion should open that result directly.
3. After selecting a suggestion by manufacturer name -> search results show part of the products from that manufacturer. (Selecting a manufacturer must show the same results as selecting it from manufacturer list)
4. In data priority -> if manufacturer is "0" (i.e. not suggest manufacturer name) module is not showing suggestions of products (any)
