Is there any way to export bigger search results then 1 000 000?
Depending on your needs there are other options of exporting data from Logger.
Exporting a smaller data set every hour automatically.
The exported data can be processed in nice handy chunks afterwards.
(I use a cron job to zip the csv's and do monthly offline statistics)
Configuring a forwarder sends the data of a query directly to your target system as data flows in.
(I use a custom syslog receiver to process the data in CEF format, but a standard syslog server will do fine.)
multiple smaller searches.
