class  Lucene.Net.Analysis.Token
 A Token is an occurrence of a term from the text of a field. It consists of a term's text, the start and end offset of the term in the text of the field, and a type string. The start and end offsets permit applications to re-associate a token with its source text, e.g., to display highlighted query terms in a document browser, or to show matching text fragments in a <abbr title="KeyWord In Context">KWIC</abbr> display, etc. The type is a string, assigned by a lexical analyzer (a.k.a. tokenizer), naming the lexical or syntactic class that the token belongs to. For example an end of sentence marker token might be implemented with type "eos". The default token type is "word". A Token can optionally have metadata (a.k.a. Payload) in the form of a variable length byte array. Use TermPositions.PayloadLength and TermPositions.GetPayload(byte[], int) to retrieve the payloads from the index. More...
