incremental merge of index

For a continuous crawling/indexing web search engine, there is usually a big
main index that is being searched on, and smaller incremental indexes
created on a daily base. What's a good strategy to merge a daily index into
the main index?  the daily index is already merged from indexes using
IndexMerger. It seems IndexMerger only works on indexes created by Indexer
(using hardcoded directory structure). Is there another tool to merge two
merged index?
thanks,
aj
