- the methods {parsing, semantic analysis (condensing), structure analysis (web structure)} in the serialized indexing path had been made concurrent.
- four BlockingQueues handle concurrency and hand-over of the indexing objects, the last object in the queue is stored into a blockingQueue of maximum size 1 to serialize the process for storage (which uses IO and therefore here should not be deserialized)
- a concurrency of (CPUs + 1) is default. Single-CPU users will profil from the change because large files cannot block the indexing process any more.
- removed the secondary indexing thread, which is superfluous now. Concurrency is default for all users.
