# Characters

The maximum number of characters that each document summary can contain. This parameter has an effect only when you set the Summary parameter. By default, there is no restriction to the number of characters that a summary can contain.

For a `Concept` or `Context` Summary, if you set both the Sentences and `Characters` parameters, IDOL Server attempts to satisfy both requirements. If it cannot apply both restrictions, it uses only the `Characters` restriction (for example, because the only sentences that contain the best terms are longer than the character restriction). If IDOL Server cannot create a concept or context summary that fits either restriction, it returns a `quick` summary.
