: There is no default value for ptime. It is generated by users. thank you, that rules out my previous wild guess.
: I was trying query with a function query({!boost b=dateDeboost(ptime)} : channelid:0082 && title:abc), which leads differents results from the same : shard(using the param: shards=shard3). : : The diffenence is maxScore, which is not consistent. And the maxScore is Ok ... but you still haven't provided enough information for us to make a guess as to why you are seeing inconsistent scores coming back form your queries -- at a minimum we need to see the debugQuery=true output for each of the different replicas that are generating differnet scores. It's possible that the descrepency you are seeing is a minor one resulting from slightly different term stats (ie: segments being merged slightly differnetly on differnet replicas), or it could be a symptom of a larger problem. -Hoss http://www.lucidworks.com/
