there are two issues to keep i mind here: one is the analyzer you choose for your fields -- for many tokenizers those "+" symbols will be split on and thrown away. use the analysis tool to see exactly how those a-f values will get indexed. second: "+" as you know is a special character -- but only if it is the first character in a string, if it appears in the middle it is not special. In the standard request handler you can escape this special character with quoting or backslash escaping (but don't use both at the same time), in dismax the only way to escape it is by enclosing your string in quotes. To debug how the query parser is dealing with your string and whether or not it's treating it as a special character, use the debugQuery=true option when you send your query and look at the "parsedquery_toString" output. query on a field that uses the KeywordAnalyzer so you can be confident that any changes you see to the string in parsedquery_toString are a result of the query parser and notthe analyzer. : I have 2 field types, title :- which is supported by dismax. : title_exact:- which does not supported by dismax. But only has : KeywordTokenizer, and Lowercase. i'm really not sure that that means ... there is no reason why you shouldn't be able to query your title_exact field with dismax -Hoss
