Our normal results cluster by site meaning that you will only see one result for each site.
When it comes to Focus, it is very likely that a different approach will be needed and so for the initial version, we have decided to completely disable site clustering. This being said it is very much an open question as to what kind of clustering would be useful.
Both theoretical and practical points are very much appreciated; you can set it manually using ‘si’, here’s an example using just regular Mojeek search:
regular, with no amends to clustering (one result/site)
si parameter added, 10 results from reddit before others
