For my private websites, which require membership and would not be accessible via search engines, I just use general SQL search queries with a combination of PHP (stristr) and the results return quickly and accurately. Just make sure you are searching case-insensitive. Just be sure to add content or tags to your e-commerce pages so you have something to pick up. For my public websites, I use DuckDuckGo ( https://duckduckgo.com/search_box https://duckduckgo.com/search_box ) which has done a great job in regards to indexing. I used to use Google search but a few times, my website was penalized, and Google kills your website in ALL searches. While I've since gotten those penalties removed, I hated that IF a penalty occurred, I had to worry about that, so in order to not deal with that anymore, I made the switch. DDG is very rarely going to ever penalize your website. I was in luck as well because Google announced they were disabling their search anyway, so I had already made the switch and had no worries.
