Hi everybody! Ahmet, do I get it correct - if I use this text_char_norm field type, for input "myName=aaa bbb" I'll index terms "myName", "aaa", "bbb"? So I'll match with query like "myName" or query like "bbb", but not match with "myName aaa". I can use this type for query value, so split "myName aaa" into ( "myName" && "aaa") - and it will work. But this approach will give false positive match with "myName bbb". What do you think, how I can handle this? One of the approaches is to use in this field type KeywordTokenizer+ShingleFilter instead of WhitespaceTokenizerFactory, so tokens like "myName", "myName aaa", "myName aaa bbb", "aaa", "aaa bbb", "bbb" will be indexed, but it significantly increased index size in case of long values.
