Question: I have this problem for a long time, and can't find a solution.
I guess this might be something everybodys faced using Sphinx, but I cnanot get any
usefull information.

I have one index, and a delta.
I queried in a php module both indexes, and then show the results.
For each ID in the result, I create an object for the model, and dsiplay main data for
that model.

I delete one document from the database, phisically.

When I query the index, the ID for this deleted document is still there (in the sphinx
result set).
Maybe I can detect this by code, and avoid showing it, but the result set sphinx gaves me
as result is wrong. xxx total\_found, when really is xxx-1.
For example, Sphinx gaves me the first 20 results, but one of this 20 results doesn't
exists anymore, so I have to show only 19 results.

I re-index the main index once per day, and the delta index, each 5 minutes.

Is there a solution for this??

Thanks in advance!!

Answer: 
Maybe this fits better to my needs, but involves changing the database.

I suppose you could ask for maybe 25 results from sphinx and then when you get the full data from your DB just have a `limit 20` on the query.
