Hi all,

is there a way (or formula) to determine the required amount of RAM memory, e.g. by number of documents, document size?

I need to index about 15.000.000 documents, each document is 1 to 3Kb big, only the id of the document will be stored.

I've just implemented a testcase on one of our older servers (only 512Mb RAM) with 4.000.000 documents, searching the index is quite fast, but when I trie to sort the results, I get the well-known OutOfMemory error. I'm aware of the fact that 512Mb is way too little, but I'm trying to determine what size will be needed for 15.000.000 documents.

Thanks in advance.
