Hi Erick Thanks for the response.
I would want the documents with values within #20-30# be ranked above the documents with some other values. Well, since there might be a case where there are no documents in that range, I would also prefer to have other documents listed too, somewhere lower down the rankings. Also, I don't want to do a simple sort on the results what lucene gives, with its own ranking function. I am looking for a possibility of boosting a given document at query-time, based on the values of a particular field : instead of plainly sorting the normal lucene results based on this field. Is that possible, without going in to the scoring function? Sowmya. ************* I take it from this that you want documents with values #outside# 20-30 to still be found? In that case you can do something like add a clause like: OR *field*:[20 TO 30]^10 or similar.
