question: partialResults true with pagination

[Vibhor Goel <vi...@limeroad.com>]

hey,

i am using single standalone solr instance. Some of my queries are taking
long time due to large number of result documents. I am using timeout
option and it returns me partial results.

i found out partial results returns a random set of resultant documents, in
sorted order.

My query is when i am using solr with pagination, I am making calls with
same query again and again. how to ensure that i wont get repetition in the
documents, as different queries return different number of resultant
documents.

And with filter cache and document cache will the situation get worse.

How can i have a work around with this problem.

Don't request a large number of documents at a time. The exact size
depends on your setup: If they are small documents you can probably get
away with tens of thousands. Asking for millions is a recipe for poor
performance.

Are you using cursorMark? You should do so, to avoid progressively worse
performance as you page deeper.
