C# Класс Lucene.Net.Analysis.Miscellaneous.CapitalizationFilter

A filter to apply normal capitalization rules to Tokens. It will make the first letter capital and the rest lower case.

This filter is particularly useful to build nice looking facet parameters. This filter is not appropriate if you intend to use a prefix query.

CapitalizationFilter() публичный Метод

Creates a CapitalizationFilter with the specified parameters.

public CapitalizationFilter ( TokenStream @in, bool onlyFirstWord, CharArraySet keep, bool forceFirstLetter, ICollection okPrefix, int minWordLength, int maxWordCount, int maxTokenLength ) : System
@in	TokenStream
onlyFirstWord	bool	should each word be capitalized or all of the words?
keep	CharArraySet	a keep word list. Each word that should be kept separated by whitespace.
forceFirstLetter	bool	Force the first letter to be capitalized even if it is in the keep list.
okPrefix	ICollection	do not change word capitalization if a word begins with something in this list.
minWordLength	int	how long the word needs to be to get capitalization applied. If the /// minWordLength is 3, "and" > "And" but "or" stays "or".
maxWordCount	int	if the token contains more then maxWordCount words, the capitalization is /// assumed to be correct.
maxTokenLength	int	???
Результат	System
