GENERATION OF SEARCH INDEX

Technologies are generally described for generating search indices. In some examples, a method performed under control of a storage device including a first memory and a second memory may include generating a first search index that corresponds to a first data stored in the first memory, based on analysis of the first data; and generating a second search index that corresponds to a second data stored in the second memory in parallel with the generating of the first search index, based on analysis of the second data.
