# QuerySummaryMaxDocLength

The maximum number of characters in each document to use to generate a query summary (for actions sent with the QuerySummary parameter, or with Summary set to `Concepts`).

NOTE: Setting a high value for `QuerySummaryMaxDocLength` can reduce performance for QuerySummary generation if IDOL contains long documents.

This parameter overrides the value of the QuerySummaryMaxDocLength configuration parameter for the action.

Actions: | Query Summarize
Type: | Long
Default: | 6000
Example: | `QuerySummaryMaxDocLength=2500`
