i’m indexing a table from some legacy db via a nightly executed  
script/runner command (LegacyInfobase.rebuild\_index).

but very often newer documents don’t show up in search results for quite  
some days. when running it manually from console for diagnosis it mostly  
stops with this error (but not always):

[This was fast-saved 1 times. Some information is lost]  
IOError: IO Error occured:  
couldn’t rename file  
“./script/…/config/…/config/…/index/production/legacy\_in  
fobase\_3d4.tmp” to  
“./script/…/config/…/config/…/index/production/legacy\_inf  
obase\_3d4.cfs”:

is it required to manually delete the existing index files before a  
rebuild?

no, usually not. But make sure nobody else uses the index while you’re  
rebuilding it. Use the DRb server if you can’t ensure this, it takes  
care then.
