Class ChainedFilter

Allows multiple Lucene.Net.Search.Filters to be chained. Logical operations such as NOT and XOR are applied between filters. One operation can be used for all filters, or a specific operation can be declared for each filter.

Order in which filters are called depends on the position of the filter in the chain. It's probably more efficient to place the most restrictive filters/least computationally-intensive filters first.

Fields

AND

Allows multiple Lucene.Net.Search.Filters to be chained. Logical operations such as NOT and XOR are applied between filters. One operation can be used for all filters, or a specific operation can be declared for each filter.

Order in which filters are called depends on the position of the filter in the chain. It's probably more efficient to place the most restrictive filters/least computationally-intensive filters first.

Declaration

public const int AND = 1

Field Value

Type	Description
int

ANDNOT

Allows multiple Lucene.Net.Search.Filters to be chained. Logical operations such as NOT and XOR are applied between filters. One operation can be used for all filters, or a specific operation can be declared for each filter.

Order in which filters are called depends on the position of the filter in the chain. It's probably more efficient to place the most restrictive filters/least computationally-intensive filters first.

Declaration

public const int ANDNOT = 2

Field Value

Type	Description
int

DEFAULT

Logical operation when none is declared. Defaults to OR.

Declaration

public const int DEFAULT = 0

Field Value

Type	Description
int

OR

Allows multiple Lucene.Net.Search.Filters to be chained. Logical operations such as NOT and XOR are applied between filters. One operation can be used for all filters, or a specific operation can be declared for each filter.

Order in which filters are called depends on the position of the filter in the chain. It's probably more efficient to place the most restrictive filters/least computationally-intensive filters first.

Declaration

public const int OR = 0

Field Value

Type	Description
int

XOR

Allows multiple Lucene.Net.Search.Filters to be chained. Logical operations such as NOT and XOR are applied between filters. One operation can be used for all filters, or a specific operation can be declared for each filter.

Order in which filters are called depends on the position of the filter in the chain. It's probably more efficient to place the most restrictive filters/least computationally-intensive filters first.

Declaration

public const int XOR = 3

Field Value

Type	Description
int
