# DRESYNC

Allows you to force an immediate flush to disk from the index cache. Sending this index action to the index port instructs the server to flush to disk and any documents currently held in the index cache are committed to disk.

This index action is required only when DelayedSync is set to `TRUE` in your configuration file, and you believe documents have been processed but are not yet available for search. If documents remain in the index cache, the GetStatus action output shows a higher number of document sections than the number of committed slots.

NOTE:

These documents are flushed anyway when the configured MaxSyncDelay period expires.

## Example

    http://Hume:20001/DRESYNC?

This index action uses port `20001` to instruct the HPE Distributed Index Handler on host `Hume` to flush all files to disk.

## Parameters

This index action accepts the following standard index action parameters.

Parameter | Description
--- | ---
IgnoreMaxPendingItems | Whether to ignore the IndexQueueMaxPendingItems limit for this index action.
IndexUID | An identification code for any document tracking events.
NoArchive | Turn off configured archiving for the index action.
Priority | The priority for the index job.
