Description

When there are very few documents in the index the ExportQParserPlugin is creating a dummy docList which is larger then the number of documents in the index. This causes a bug during the prefetch stage of the QueryComponent.

There really needs to be two fixes here.

1) The dummy docList should never be larger then the number of documents in the index.

2) Prefetch should be turned off during exports as it's not doing anything useful.
