Currently the maximum size of a single document is limited to 1 MByte. That is an artificial limitation resulting from the fact, that SeekStorm does not only indexes the content of the document, but also stores the original document.
Somewhere there has to be a limit.
SeekStorm is intended that the user can index and search their own private data.
But if there is demand we could also allow to search in a central public index for web data or other public data.
