Hi all, I am trying to upgrade to Lucene 6.6.0. I see that index time field level boosting via Field#setBoost is now deprecated.
The suggested replacement is a FunctionScoreQuery at query time. I am using the MultiTermQueryParser to search an arbitrary user-supplied query string against multiple indexed fields. FunctionScoreQuery seems appropriate to apply an indexed boost value against a Query which might represent only a single Field. However it is not clear to me how one decomposes a MultiTermQuery and then applies the indexed boost value to each field as it appears in the rewritten query. Could someone please illustrate the suggested way to replace index time field level boosting now that it has been deprecated? In particular, it would be helpful to know how one rewrites a MultiTermQuery to apply the indexed boost values against each field at query time. Thank you very much in advance! - Matt
