I think that's probably the only way to do this effectively, but how can I specify a particular analyzer on a per-model-instance basis? I only recall seeing that aaf allows analyzer specification on a per-model basis. Or perhaps you were thinking of a single analyzer that does heuristics itself and decides how to tokenized based on the input string? > No, that's correct.

The first rebuild_index will probably take many hours, and, while that's building, thousands on new model instances will be created. Since we can't turn on automatic indexing (at least until the index is up to date), how do we get the index up to date? > Index updates are synchronized as there only may be one thread writing > to the index at a time.

That's fine- it certainly beats the typical latency that already we get from Google crawlers, which are currently our only local search functionality.
