Hi, I just found the root cause. The definition for the 'long' type is not right. the previous definition was:
<fieldType name="long" class="solr.LongField" omitNorms="true"/> which doesn't support range query! now I changed to : <fieldType name="long" class="solr.TrieLongField" precisionStep="8" omitNorms="true" positionIncrementGap="0"/>, and it's done! Thanks a lot!

What version of Solr are you using? What is your complete handler definition?
