public sealed class LengthFilter : FilteringTokenFilter, IDisposable

Constructors

LengthFilter(LuceneVersion, TokenStream, int, int)

Create a new LengthFilter. This will filter out tokens whose Lucene.Net.Analysis.TokenAttributes.ICharTermAttribute is either too short (Lucene.Net.Analysis.TokenAttributes.ICharTermAttribute.Length < min) or too long (Lucene.Net.Analysis.TokenAttributes.ICharTermAttribute.Length > max).

Declaration
public LengthFilter(LuceneVersion version, TokenStream @in, int min, int max)
Parameters
Type Name Description
LuceneVersion version

the Lucene match version
TokenStream in

the Lucene.Net.Analysis.TokenStream to consume
int min

the minimum length
int max

the maximum length

LengthFilter(LuceneVersion, bool, TokenStream, int, int)

Declaration
[Obsolete("enablePositionIncrements=false is not supported anymore as of Lucene 4.4.")]
public LengthFilter(LuceneVersion version, bool enablePositionIncrements, TokenStream @in, int min, int max)
Parameters
Type Name Description
LuceneVersion version
bool enablePositionIncrements
TokenStream in
int min
int max

Methods
