Should I expect different results if I use ranker=bm25 vs ranker=expr('bm25') while retrieving documents?
I am getting different results when I use either. I can provide more details/examples but would like to understand if I am using the ranker and expr correctly.
Thanks!
it could be better to create ticket at github there provide minimal reproducible example with confit, data, queries along with result sets
I’ll create a ticket on github with a minimal reproducible example. But can you confirm that ranker=bm25 and ranker=expr('bm25') are equivalent and should return the same results?
Since it’s said here Manticore Search Manual: Searching > Sorting and ranking
- bm25 =
bm25
which means ranker=bm25 = ranker=expr('bm25')
it should be so. If it’s not true then it’s a bug and should be investigated.
