I want to filter documents from a list of values.  
Say, i have an index which contains a field "customer\_id".  
I have a list of customer\_ids to lookup from the above index and the list is around 10000 ids.  
Is there any efficient way to index these ids somewhere and use them in the query ?  
I am skeptical about sending such huge bunch of ids every time i want to filter them in the query.

Please let me know if you have come across such situation.  
Thanks!
