Hi all, I am running Lucene 3.6 in a system that indexes about 4 billion documents across several indexes, and I'm hoping to get documents in order of a certain NumericField.
I've tried using Lucene's Sort implementation, but it looks like it tries to do the entire sort in memory by allocating a huge array with space for every document in the index. On my index, this quickly runs out of memory. Instead, I've switched to using several NumericRangeQueries to approximate getting documents in a certain order. However, NumericRangeQueries seem slow. Are there any alternatives or better ways of getting documents in order of a NumericField for a very large index? -- Rob
