How to turn TF off (that is a single term in a field is the same as multiple ones) in scoring (keeping IDF and field length)? -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

You can turn off tf, but you also have to turn off positions at the same time. (There is no positions without term frequency). This implies you won't be able to do a phrase query.

Thanks! Having norms on and docs for index\_options will we keep scoring on the field length? - that is "abc" in "abc" has more score than in "abd def". In other words, do norms include field-length-based scoring factor?

You can "disable" TF by multiplying it with itself. This requires adding a configuration in the base similarity module I think. I have not tried this yet, so please let us know if this will work! /JZ -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
