Adrien Grand	458bca11bc	Add a `feature_vector` field. (#31102 ) This field is similar to the `feature` field but is better suited to index sparse feature vectors. A use-case for this field could be to record topics associated with every documents alongside a metric that quantifies how well the topic is connected to this document, and then boost queries based on the topics that the logged user is interested in.

Adrien Grand	886db84ad2	Expose Lucene's FeatureField. (#30618 ) Lucene has a new `FeatureField` which gives the ability to record numeric features as term frequencies. Its main benefit is that it allows to boost queries with the values of these features and efficiently skip non-competitive documents at the same time using block-max WAND and indexed impacts.	2018-05-23 08:55:21 +02:00

sparse feature vectors. A use-case for this field could be to record topics
associated with every documents alongside a metric that quantifies how well
the topic is connected to this document, and then boost queries based on the

Expose Lucene's FeatureField. (#30618 )

Lucene has a new `FeatureField` which gives the ability to record numeric
features as term frequencies. Its main benefit is that it allows to boost
queries with the values of these features and efficiently skip non-competitive
documents at the same time using block-max WAND and indexed impacts.
