# Characters

The number of characters that each summary can contain. By default the number of characters that summaries contain are not restricted.

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 (for example, because the only sentences that contain the best terms are longer than the character restriction), it uses only the `Characters` restriction. If IDOL Server cannot create a concept or context summary that fits either restriction, it returns a `quick` summary.

This parameter has no effect when you set Summary to `Concepts`.
