What are optimal approaches for infix substring search indexes when backed by an ordered key-value store?

I need to quickly substring search up to 500 million unique strings, each less than 256 chars in length. This needs to support substring matching ("bcd" in "abcde"); and I'll constantly be adding new/existing strings to the index.



What approaches to this problem may be best suited to taking advantage of the ordered nature of my backing key-value store (think leveldb, for instance)?






algorithm search indexing full-text-indexing
