Multiplicative boosts tend to be more stable... Perhaps try replacing bf=isflag sqrt(popularity) with bq=isflag:true^10 // vary the boost to change how much isflag counts vs the relevancy score of the main query boost=sqrt(popularity) // this will multiply the result by sqrt(popularity)... assumes that every document has a non-zero popularity You could get more creative in trunk where booleans have better support in function queries. -Yonik http://www.lucidimagination.com
