Disable cache?

(from github.com/defensivedepth)
Is there a way to disable caching of crawled pages? I am trying to reduce storage requirements for a project, and figured I can minimize storage requirements if I can disable the caching of images, etc.

The setting is in fess_config.properties.
To disable a page cache, set false to:

crawler.document.cache.enabled=false

Thanks, much appreciated!

Hello github.com/defensivedepth
How much space utilisation is reduced by disabling the cache?
