org.apache.lucene.search.CollectionStatistics

record final extends Record 9 members

Contains statistics for a collection (field).

This class holds statistics across all documents for scoring purposes:

#maxDoc(): number of documents.
#docCount(): number of documents that contain this field.
#sumDocFreq(): number of postings-list entries.
#sumTotalTermFreq(): number of tokens.

The following conditions are always true:

All statistics are positive integers: never zero or negative.
docCount <= maxDoc
docCount <= sumDocFreq <= sumTotalTermFreq

Values may include statistics on deleted documents that have not yet been merged away.

Be careful when performing calculations on these values because they are represented as 64-bit integer values, you may need to cast to double for your use.

Constructors

new

new ( String field, long max_doc, long doc_count, long sum_total_term_freq, long sum_doc_freq )

Java: <init>(String field, long maxDoc, long docCount, long sumTotalTermFreq, long sumDocFreq)

Creates statistics instance for a collection (field).

Throws

IllegalArgumentException	if `maxDoc` is negative or zero.
IllegalArgumentException	if `docCount` is negative or zero.
IllegalArgumentException	if `docCount` is more than `maxDoc`.
IllegalArgumentException	if `sumDocFreq` is less than `docCount`.
IllegalArgumentException	if `sumTotalTermFreq` is less than `sumDocFreq`.
