I'm sorry but that behaviour is very, very flaky in Duckduckgo and breaks for me regularly.
Filtering retailers out of search results in Duckduckgo can be very difficult because of it.
An trivial example that springs to mind recently was trying to search for information on the manufacturer of Hycosan Extra eye drops.
The results are swamped by ecommerce sites with no actual information on them. Adding terms like "-pharmacist" or "-retailer" actually boosts sites with pharmacist in their URL to the top of the results.
I sometimes have the same issue searching for programming topics where the results are swamped by Microsoft related tech. That would be fine if that's what I was searching for but when it's not it's a real pain in the arse. Using "-microsoft" or some other exclusion just boosts the incorrect results from Microsoft's own site even further.
Sometimes Duckduckgo fix this behaviour but it seems to break randomly for me.
