IndriAndScorer

class IndriAndScorer(subScorers: MutableList<Scorer>, scoreMode: ScoreMode, boost: Float) : IndriDisjunctionScorer

Combines scores of subscorers. If a subscorer does not contain the docId, a smoothing score is calculated for that document/subscorer combination.

Constructors

IndriAndScorer

constructor(subScorers: MutableList<Scorer>, scoreMode: ScoreMode, boost: Float)

Properties

children

open val children: MutableCollection<Scorable.ChildScorable>

minCompetitiveScore

open var minCompetitiveScore: Float

Optional method: Tell the scorer that its iterator may safely ignore all documents whose score is less than the given minScore. This is a no-op by default.

Functions

advanceShallow

open fun advanceShallow(target: Int): Int

Advance to the block of documents that contains target in order to get scoring information about this block. This method is implicitly called by and DocIdSetIterator.nextDoc on the returned doc ID. Calling this method doesn't modify the current DocIdSetIterator.docID. It returns a number that is greater than or equal to all documents contained in the current block, but less than any doc IDS of the next block. target must be >= .docID as well as all targets that have been passed to .advanceShallow so far.

docID

open override fun docID(): Int

Returns the doc ID that is currently being scored.

getBoost

fun getBoost(): Float

getMaxScore

open override fun getMaxScore(upTo: Int): Float

Return the maximum score that documents between the last target that this iterator was .advanceShallow to included and upTo included.

getSubMatches

fun getSubMatches(): MutableList<Scorer>

iterator

open override fun iterator(): DocIdSetIterator

Return a DocIdSetIterator over matching documents.

score

open override fun score(subScorers: MutableList<Scorer>): Float

open override fun score(): Float

Returns the score of the current document matching the query.

smoothingScore

open override fun smoothingScore(subScorers: MutableList<Scorer>, docId: Int): Float

open override fun smoothingScore(docId: Int): Float

Returns the smoothing score of the current document matching the query. This score is used when the query/term does not appear in the document, and behaves like an idf. The smoothing score is particularly important when the Scorer returns a product of probabilities so that the document score does not go to zero when one probability is zero. This can return 0 or a smoothing score.

twoPhaseIterator

open fun twoPhaseIterator(): TwoPhaseIterator?

Optional method: Return a TwoPhaseIterator view of this Scorer. A return value of null indicates that two-phase iteration is not supported.
