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.

Note

This API is experimental and might change in incompatible ways in the next release.

Syntax

public static class MultiDocValues

Methods

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
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
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

Type	Name	Description
IndexReader	r
string	field

Returns

Type	Description
NumericDocValues

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

Type	Name	Description
IndexReader	r
string	field

Returns

Type	Description
NumericDocValues

GetSortedSetValues(IndexReader, string)

Returns a SortedSetDocValues for a reader's docvalues (potentially doing extremely slow things).

This is an extremely slow way to access sorted values. Instead, access them per-segment with GetSortedSetDocValues(string)

Declaration

public static SortedSetDocValues GetSortedSetValues(IndexReader r, string field)

Parameters

Type	Name	Description
IndexReader	r
string	field

Returns

Type	Description
SortedSetDocValues

GetSortedValues(IndexReader, string)

Returns a SortedDocValues for a reader's docvalues (potentially doing extremely slow things).

this is an extremely slow way to access sorted values. Instead, access them per-segment with GetSortedDocValues(string)

Declaration

public static SortedDocValues GetSortedValues(IndexReader r, string field)

Parameters

Type	Name	Description
IndexReader	r
string	field

Returns

Type	Description
SortedDocValues
