Abstract
Official abstract text for this publication.
A method begins by a dispersed storage (DS) processing module receiving a request to retrieve a data object based on a search attribute. The method continues with the DS processing module retrieving and decoding a set of encoded index data slices to reconstruct an index file. The method continues with the DS processing module identifying a child index file, retrieving and decoding a set of encoded child index data slices to reconstruct the child index file, and determining whether the child index file includes a dispersed storage network (DSN) address for the data object. When the child index file includes the DSN address for the data object, the method continues with the DS processing module retrieving a plurality of sets of encoded data slices based on the DSN address and decoding the plurality of sets of encoded data slices to recapture the data object.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for execution by a processing module, the method comprises: receiving a request to retrieve a data object, wherein the request includes a search attribute regarding the data object; determining a dispersed storage network (DSN) address for an index file based on the search attribute; retrieving a set of encoded index data slices from a DSN based on the DSN address; decoding the set of encoded index data slices to reconstruct the index file, wh…
