At this point, only the datetime deltas use merging... when I tried to get merging working with standard deltas, I found it unreliable. That was over a year ago, though, so maybe things have changed.
However, with real-time indexes now appearing in the latest Sphinx beta, hopefully we can get that into Thinking Sphinx over the coming months. -- Pat On 28/07/2010, at 1:28 PM, nnn wrote: > =quote from http://www.sphinxsearch.com/docs/current.html > 3.12.
