REQUEST: Advanced Search Module

Hi,

I am looking for a search extension that features autocorrect, autosuggest, results sorting, custom keyword links (for e.g. when the users type "delivery" and press search, it redirects them to the delivery section page), custom spell checks etc.

I know there are already quite a few available in the marketplace, however I would like to know the best option for a store with over 10000 products. Thanks in advance.

Any extension can handle any amount of products. The search speed and protection from "MySQL server has gone" error depends mostly of how good your database indexes. By default OpenCart lacks a few indexes for most popular tables, but this can be easily fixed. So just take your pick, don't worry much about number of products in your store.
