EPTAnd Mystlord, Badjas is correct. Updates right now takes less than a second, but will grow as more data since the last full index is added. I actually had to index everything four times today to get everything how I wanted it.

Ok then never mind  . I don't think there are any major problems with the new search engine then. The edit thing might be a problem because we'd lose a lot of new material (I'm thinking updates to topics like Stylish FPVODs and Day[9] podcasts).Regardless, if I find any bugs, then I'll report them here. | ||

I've worked with Lucene extensively in the past, and it has top-notch performance, and it can be coded to address all of your problems. Maybe you can have a look when you are really bored over the holidays. I'll definitely have a look at Sphinx  Good job re-writing the search engine though! Regarding the non-edit problem, can't you delete contents from the indices, and then simply re-index edited contents? | ||

Given that: Building indices from scratch takes 30 minutes Incremental updates take much less time What we can do is keep two sets of indices, call them A and B. Find a time when TL is least busy (i.e. least stress on the server) and call this time T. We incrementally update one set of indices, A, until time T; at time T, we completely remove the other set of indices, B, and rebuild it from scratch. While B is being built, we obviously still update A, and all search queries will be run against A. After B is complete, we "dump" A, and run all subsequent queries against B. And we switch B with A again at time T. This way, the indices will be 1-day stale in the worst case. Is this feasible? | ||

. It is on their todo list for a more flexible index format though. See http://www.sphinxsearch.com/docs/manual-0.9.9.html#conf-mva-updates-poolEDIT: TL doesn't really have an off-peak time, however the indexer can use a configurable IOPS, iosize and delay so if we want it to take 4 hours to update, it can. Refreshing the index every day like this is certainly possible, but I'd rather avoid it since even with very conservative settings, it's still going to suck up a lot of RAM and IO. Maybe a weekly update is doable. | ||

A full rebuild would be good every now and then regardless to minimize the size of the delta index. It would probably improve performance as well. Lucene definitely didn't like incremental indexing (and updates) as much as I'd liked. Maybe suggest an "optimize" function to re-organize the existing index if such method doesn't exist yet? | ||
