geocoding - postgis vs sphinx geodist -


i have table 16 mln rows. cities, streets, houses coordinates.

how best search objects, knowing coordinates? postgis or sphinx geodist function?

now using sphinx, there question relevance of data update of index takes more 4 hours, , indexing delta following merge main takes 10 minutes.

mainly depends on other features require. example if using text query functionality of sphinx, stick it.

but if not using anyway, , can benefit of other features of postgis, change that.

indexing delta following merge main

why merge?

skip merge, , query both indexes.
