I've read a bunch of the wiki's on solr heap usage and wanted to confirm my understanding of what all does solr use the heap for:
1. Indexing new documents - until committed? if not how long are the new documents kept in heap? 2. Merging segments - does solr load the entire segment in memory or chunks of it? if later how large are these chunks 3. Queries, facets, caches - anything else major? John
