Abstract: According to an aspect, a search system includes an indexing tier and a search tier. The indexing tier is configured to generate an index structure from a plurality of documents, store the index structure in a local storage device, and transmit the index structure to an external object store, the external object store configured to store the index structure. The search tier is configured to receive a search query from a client device and communicate with the external object store or the indexing tier to retrieve at least a portion of the index structure to search data based on the search query.

Abstract: Provided are systems and methods for multi-layer caching of data. An example method commences with creating a data structure on top of an information retrieval library. The data structure is designed to access data associated with the information retrieval library through a local index. The method includes creating a plurality of ordered cache layers for the data accessed via the local index. 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. The method then continues with receiving a search query. The method further includes determining that the search query is for the data associated with the last layer. The method further continues with executing, using the local index, the search query locally to retrieve a matching document from the data associated with the last layer remotely.

Abstract: Methods and systems for shard optimized database queries using parameter-based indexes are provided. Exemplary methods include: receiving a database query that includes an index parameter and an index parameter range. A parameter table is accessed that contains an association between the parameter and parameter range and a shard identifier. Based on the parameter type and the range identified in the query, the relevant shards are identified, and the database query is limited to processing these shards.
