Say your model produces a set of weighted terms: - At index time, for each (term, weight) pair, you add a "new FeatureField(fieldName, term, weight)` field to your document. - At search time, for each (term, weight) pair, you add a "new BooleanClause(FeatureField.newLinearQuery(fieldName, term, weight))" to your BooleanQuery.
