typesense

if no `default_sorting_field` is provided in the schema what's the order returned? insertion order?

`_text_match:desc` by default (textual relevance) and if there's a tie, then insertion order, yes

ok, cool cause in my case the query is empty

how much does sort_by impact performance?

There's some level of sorting always happening when results are returned - we need to order results somehow

Where you might see a performance cost is when you sort by multiple fields and a lot of record tie on fields earlier in the sort_by list, so additional fields need to be used for tie-breaking
