Technical Notes

Once the extension is correctly configured, you should see the following graphical blocks: facets (if defined in Search Engine Configuration), sort orders, pager, and spellcheck (when keyword was approximative). If at least one block is missing, do not worry, it surely comes from a customization in your Magento Templates. Try to modify the layout so it finds missing blocks.
