I personally don't know how the end user will interact with my website. Therefore, it's more or less impossible for me to actually decide which search format I should use. I really don't know whether my users will be using natural search query's or just simple old keywords.
Could someone kindly suggest what would work more effectively for a digital e-commerces website? At the moment, I'm using both in conjunction, I don't know if that's a good or bad approach.
I should mention, it's been a couple of days since I've introduced the search feature.
