 * @deprecated Index-time boosting will not be possible anymore starting from Lucene 7.
 * You should use query-time boosting instead, for instance by calling
 * {@link org.hibernate.search.query.dsl.FieldCustomization#boostedTo(float) boostedTo(float)}
 * when building queries with the Hibernate Search query DSL.
