Struct tantivy::postings::BlockSegmentPostings [−][src]
pub struct BlockSegmentPostings { /* fields omitted */ }
Expand description
BlockSegmentPostings
is a cursor iterating over blocks
of documents.
Warning
While it is useful for some very specific high-performance
use cases, you should prefer using SegmentPostings
for most usage.
Implementations
pub fn block_max_score(
&mut self,
fieldnorm_reader: &FieldNormReader,
bm25_weight: &Bm25Weight
) -> Score
[src]
pub fn block_max_score(
&mut self,
fieldnorm_reader: &FieldNormReader,
bm25_weight: &Bm25Weight
) -> Score
[src]Returns the block_max_score for the current block.
It does not require the block to be loaded. For instance, it is ok to call this method
after having called .shallow_advance(..)
.
See TermScorer::block_max_score(..)
for more information.
Returns the overall number of documents in the block postings. It does not take in account whether documents are deleted or not.
This doc_freq
is simply the sum of the length of all of the blocks
length, and it does not take in account deleted documents.
Returns the array of docs in the current block.
Before the first call to .advance()
, the block
returned by .docs()
is empty.
Return the array of term freq
in the block.
Returns the length of the current block.
All blocks have a length of NUM_DOCS_PER_BLOCK
,
except the last block that may have a length
of any number between 1 and NUM_DOCS_PER_BLOCK - 1
Position on a block that may contains target_doc
.
If all docs are smaller than target, the block loaded may be empty, or be the last an incomplete VInt block.
Advance to the next block.
Returns false iff there was no remaining blocks.
Returns an empty segment postings object
