Maybe I’m not connecting to the host correctly (I’m using the name my PC and port 3312 with searchd listening on that same port). I’ve also tried with my local IP address. I would have thought if my connection was wrong it’d error earlier on in the code but it doesn’t even if I deliberately but an incorrect host and port.

Any pointers would be great – thanks.

Thanks for this library, I wonder if it allows real time index, I want to use that new feature, available since sphinx 1.10.

Adding to the index is done through the sphinx indexer, not this client api. The indexer can be configured to query your database incrementally to keep your index up to date. I have it doing index updates every 15 minutes, which is plenty fast for my users needs.

Question – does your API include methods to add text to the index or do I do that separately?

Thanks…
