# MaxIndexSizeKb

The maximum combined size of all the IDOL Server index directories. When the limit is reached, IDOL Server returns the `<FULL>` flag in the GetStatus action.

By default, the value of the `<full_ratio>` tag in the GetStatus action is the ratio of the number of documents in IDOL Server to the value of the MaxDocumentCount configuration parameter. If you do not set MaxDocumentCount, the `<full_ratio>` is determined by `MaxIndexSizeKb`.

To prevent loss of data, engines that are marked as full continue to process index actions. The `<FULL>` marker is a guide for the component that sends index actions to the server. For example, DIH does not send index actions to full engines when you configure it with the `RespectChildFullness` parameter set to `True`. For more details, refer to the DIH Administration Guide.
