Abstract: Techniques of federation of data during query time are disclosed herein. One example technique includes upon receiving an indication of interaction of a file by a user of a tenant, determining whether automatic replication of the file to a user shard corresponding to the user is permitted according to a company policy or a legal requirement, the user shard being in a second geographic region. The example technique can then include when automatic replication of the file is not permitted, storing the file in a tenant shard corresponding to the tenant in a network storage in the first geographic region and instead of replicating the file to the user shard in the second geographic region, creating, in the user shard in the second geographic region, a file reference that is a pointer to the file stored in the tenant shard in the network storage in the first geographic region.

Abstract: Content in a digital item is analyzed to identify individual terms. A count of at least some of the individual terms is obtained. A measure of the likelihood that the content is or contains natural language is obtained based on the count of at least some of the individual terms. If the measure of the likelihood that the content of the digital item is or contains natural language is above a threshold, the content of the digital item is forwarded to an indexer of a search engine. Otherwise, if the measure of the likelihood that the content of the digital item is or contains natural language is below the a threshold, the content of the digital item is not forwarded to the indexer or the content of the digital item is forwarded to the indexer together with the measure of the likelihood.
