Hey Ashwin, We, at Auto-Suggest, had the similar requirement. We wanted to boost suggestions as per their demand. For this, we also introduced a new *integer* field *demand*. We simply boosted it by (we use some mathematical transformations so showing the basic version here):
*&boost=demand* We use eDismax query parser. Since this is a numeric field, you get the uninverted index (uninvertible = true) by default. Anyways, as the recommendations in docValues section <https://lucene.apache.org/solr/guide/8_1/docvalues.html#sorting-faceting-functions> suggests using docValues for fields on you expect to do faceting, sorting and function queries, we enabled docValues for demand and tried the performance gain in using boost for demand. *Well, we didn't see any significant gains by enabling docValues on a numeric field. * On Mon, 16 Sep 2019 at 12:57, Ashwin Ramesh <ash...@canva.com> wrote: > Hi everybody, > > We have a usecase where we want to push a popularity boost for each > document in our collection.
