Multi-Level Cache System For Reduction Of Storage Costs

A method for multi-layer caching of data, the method comprising:

• creating a data structure on top of an information retrieval library, the data structure being designed to access data associated with the information retrieval library through a local index;
• creating a plurality of ordered cache layers for the data accessed via the local index, wherein the plurality of ordered cache layers are ordered based on frequency of access and a last layer is used to access the data over a network;
• receiving a search query;
• determining that the search query is for the data associated with the last layer;
• and
• using the local index, executing the search query locally to retrieve a matching document from the data associated with the last layer remotely.

A non-transitory computer-readable storage medium having embodied thereon instructions, which when executed by at least one processor, perform steps of a method, the method comprising:

• creating a data structure on top of an information retrieval library, the data structure being designed to access data associated with the information retrieval library through a local index;
• creating a plurality of ordered cache layers for the data accessed via the local index, wherein the plurality of ordered cache layers are ordered based on frequency of access and a last layer is used to access the data over a network;
• receiving a search query;
• determining that the search query is for the data associated with the last layer;
• and
• using the local index, executing the search query locally to retrieve a matching document from the data associated with the last layer remotely.
