Class MultiDocValues

A wrapper for CompositeReader providing access to DocValues.

NOTE: for multi readers, you'll get better performance by gathering the sub readers using Context to get the atomic leaves and then operate per-AtomicReader, instead of using this class.

NOTE: this is very costly.

GetBinaryValues(IndexReader, String)

Returns a BinaryDocValues for a reader's docvalues (potentially merging on-the-fly)

This is a slow way to access binary values. Instead, access them per-segment with GetBinaryDocValues(String)

Declaration
public static BinaryDocValues GetBinaryValues(IndexReader r, string field)
Parameters
Type Name Description
IndexReader r
System.String field
Returns
Type Description
BinaryDocValues

GetDocsWithField(IndexReader, String)

Returns a IBits for a reader's docsWithField (potentially merging on-the-fly)

This is a slow way to access this bitset. Instead, access them per-segment with GetDocsWithField(String)

Declaration
public static IBits GetDocsWithField(IndexReader r, string field)
Parameters
Type Name Description
IndexReader r
System.String field
Returns
Type Description
IBits

GetNormValues(IndexReader, String)

Returns a NumericDocValues for a reader's norms (potentially merging on-the-fly).

This is a slow way to access normalization values. Instead, access them per-segment with GetNormValues(String)

Declaration
public static NumericDocValues GetNormValues(IndexReader r, string field)
Parameters

GetNumericValues(IndexReader, String)

Returns a NumericDocValues for a reader's docvalues (potentially merging on-the-fly)

This is a slow way to access numeric values. Instead, access them per-segment with GetNumericDocValues(String)

Declaration
public static NumericDocValues GetNumericValues(IndexReader r, string field)
Parameters

IndexReader r
System.String field
Returns
Type Description
NumericDocValues

IndexReader r
System.String field
Returns
Type Description
