We require Sphinx search installing and integrating with our PHP site and MySQL database. The project is in two parts
1. Provide product search and display results together with price, product thumbnail image etc to match the way products are displayed in a category.
2. To leverage Sphinx to perform faceted search to populate categories, and category sort options faster instead if using current queries.
Our database has around 4.3 million products.
If you require any more details please ask.
