Possible error in similarity documentation #46058
Description
Regarding the similarity documentation, it is explained how we may use TFIDF or BM25 by including a "similarity" option when creating a field. However, this results in an error:
The [classic] similarity may not be used anymore. Please use the [BM25] similarity or build a custom [scripted] similarity instead.
This seems consistent with this old discussion:
Disallow the classic (TF-IDF) similarity on 6.0 indices.
Perhaps this other discussion finally offered an alternative:
Add a scripted similarity.
It seems like the documentation should be updated to reflect these changes. Thanks!
