With few index partitions, you it is sufficient to ask for startAt +numNeeded docs from each partition and sort globally. Normally if you wanted 10 for the first page, you would ask for 10 from each server and cache the remainder. It is better to ask for more later if the user asks for page ten. When you get up to 60 partitions, you should make it a multi stage process. Assuming your partitions are disjoint and evenly distributed, estimate the number of documents that will appear in the final result from each.
yes, partitions distrbuted. Double or triple that (and put a minimum
threshold), try to assemble the number of documents you require, and if one partition "runs out" of docs before it is done, request a new round.
i dont' know what u mean "runs out" one user request will generate 60 partitions request. they work in parallel。 so i don't know every partion's status before they done. To promise 10 page result sorted by score correctly, the only way seems to get 100 results(rows=100) from each partitioin. but it very slow. now i wanna find a way to get result sorted by score correctly and search fast. -Mike
Thks Mike. But it not i want. -- regards jl
