Skip Scoring more than once if search term appears multiple time in Document

[AmitaS (Amitha Shenoy)]

HI
Is it possible not to increase score if the search term appears in document more than once?
to implement similar to this ,which is implemented on db

            int rank = 100;
            var isMatched = false;
            if (!string.IsNullOrEmpty(field1) && field1.Contains(keyword))
            {
                rank = 1;
                isMatched = true;
            }
            else if (!string.IsNullOrEmpty(field2) && field2.Contains(keyword))
            {
                rank = 10;
                isMatched = true;
            }

Hi,

You can copy the text data fields used for your search with copy_to and keep only one occurrence of each token by using the unique token filter

Phrase search won’t work on these fields.
