: Given a list of prefixes, what is the simplest way to match them against : a text field, giving preference to shorter term matches?
I would suggest using Edge based NGrams, sorting on a numeric field containing the "length" of the term. : * Term frequency within the field must be ignored when scoring. You can omit term frequeny info when indexing (sorting will make it irrelevent, but no reason to waste the space) : * Documents and fields are sometimes boosted at index time; norms are : present. Hmmm, well that makes the sorting more complicated, but in that case you can either include the boost value into your special "length" field to have your own magic number for sorting the results, or you use a function query based approach to meld the (norm influenced) score with your own length field. -Hoss
