Hi I have a Very large number (say 3 million) of frequently changing Small indexes. 90% of these indexes contain about 50 documents, while a few 2-3% indexes have about 100,000 documents each (these being the more frequently used indexes). Each index belongs to a signed in user, thus can have unpredictable index changes, in short periods of time, or can be stagnant for a long time. What kind of indexing policy (mergefactor, maxmergedocs) would be optimal for this kind of index. Is optimizing for this kind of index needed? or wise?, if yes, what would be a good way to optimize (please note number of indexes are very large).
Any suggestions would be very helpful. -- Thanks Naveen Kumar
