Info

Arguments: maxTokenLength: (integer, default 255) Solr ignores tokens that exceed the number of characters specified by maxTokenLength. Example: In: "Please, email john.doe@foo.com by 03-09, re: m37-xq." Out: "Please", "email", "john.doe", "foo.com", "by", "03", "09", "re", "m37", "xq" Classic Tokenizer The Classic Tokenizer preserves the same behavior as the Standard Tokenizer of Solr versions 3.1 and previous. It does not use the Unicode standard annex UAX#29 word boundary rules that the Standard Tokenizer uses. This tokenizer splits the text field into tokens, treating whitespace and punctuation as delimiters. Delimiter characters are discarded, with the following exceptions: Periods (dots) that are not followed by whitespace are kept as part of the token. Words are split at hyphens, unless there is a number in the word, in which case the token is not split and the numbers and hyphen(s) are preserved. Recognizes Internet domain names and email addresses and preserves them as a single token. Factory class: solr.ClassicTokenizerFactory Arguments: maxTokenLength: (integer, default 255) Solr ignores tokens that exceed the number of characters specified by maxTokenLength. Example: In: "Please, email john.doe@foo.com by 03-09, re: m37-xq." Out: "Please", "email", "john.doe@foo.com", "by", "03-09", "re", "m37-xq" Keyword Tokenizer This tokenizer treats the entire text field as a single token. Factory class: solr.KeywordTokenizerFactory Arguments: None Example: Apache Solr Reference Guide 6.0 110
In: "Please, email john.doe@foo.com by 03-09, re: m37-xq." Out: "Please, email john.doe@foo.com by 03-09, re: m37-xq." Letter Tokenizer This tokenizer creates tokens from strings of contiguous letters, discarding all non-letter characters. Factory class: solr.LetterTokenizerFactory Arguments: None Example: In: "I can't." Out: "I", "can", "t" Lower Case Tokenizer Tokenizes the input stream by delimiting at non-letters and then converting all letters to lowercase. Whitespace and non-letters are discarded. Factory class: solr.LowerCaseTokenizerFactory Arguments: None Example: In: "I just LOVE my iPhone!" Out: "i", "just", "love", "my", "iphone" N-Gram Tokenizer Reads the field text and generates n-gram tokens of sizes in the given range. Factory class: solr.NGramTokenizerFactory Arguments: minGramSize: (integer, default 1) The minimum n-gram size, must be > 0. maxGramSize: (integer, default 2) The maximum n-gram size, must be >= minGramSize.
