Re: Boosting exact match fields.
In addition to what was proposed We use the technic described here https://github.com/cominvent/exactmatch and it works quite well.

Re: Boosting exact match fields.
In addition to what Erick correctly proposed, are you storing norms for your field of interest ( to boost documents with shorter field values )? If you are, I find suspicious "Sony Ear Phones" to win over "Ear Phones" for your "Ear Phones" query. What are the other factors currently involved in your relevancy score calculus ?

Re: Boosting exact match fields.
If these are the complete field, i.e. your document contains exactly "ear phones" and not "ear phones are great" use a copyField to put it into an "exact_match" field that uses a much simpler analysis chain based on KeywordTokenizer (plus, perhaps things like lowercaseFilter, maybe strip punctuation and the like". Then you add a clause on exact_match boosted really high.

Boosting exact match fields.
Hi, I have documents with a field (data type definition for that field is below) values as ear phones, sony ear phones, philips ear phones. when i query for earphones sony ear phones is the top result where as i want ear phones as top result. please suggest how to boost exact matches. PS: I have earphones => ear phones in my synonyms.txt and the datatype definition for that field keywords is REGARDS, Naveen
