Limiting the Quick View Size in Search Interfaces With the .NET Interface Editor

The Coveo .NET Front-End Quick View for large documents will necessarily take more space in the index and therefore take significantly more time to load when the end user clicks the Quick View link in the search interface.

As an administrator, you can set a limit on the size of the Quick View file that is downloaded in Coveo .NET search interfaces. The purpose of this limit is to ensure that the Quick View of large documents still appears relatively quickly. The inconvenient however is that when this limit is reached, the document displayed in the Quick View will be truncated, allowing users to only review the beginning of the document.

The Maximum Quick View Size parameter default value, 5 MB, should allow to display all Quick View documents within an acceptable short time, even for mobile devices or older desktop computers with limited memory. Consider increasing this value when your index contains a fair number of large documents and the Quick View truncation becomes an issue. When most devices accessing the search interface are configured with a few GB of memory, a limit of 50 MB is probably a more optimal value.

You can set the limit at the hub level to set a default size for all search interfaces in the hub, but also overwrite the limit for individual search interfaces. The limits apply to both the original and enhanced Quick Views (see About the Enhanced Quick View).
