Systems and methods for clustered inventory management

Abstract:

An inventory management system may have at least one document database and a search server. The search server may have a data structure engine storing a hierarchical data structure, at least one indexing engine, and a non-transitory computer readable medium having instructions, wherein the instructions, when executed by a processor cause the search server to receive an input document, parse one or more sub documents from the input document, prepare a search document based on the one or more sub documents, and update, by the data structure engine, the hierarchical data structure based on the search document. The search engine may further construct a relationship query based on a query for information and the hierarchical data structure, determine one or more sub documents responsive to the relationship query based on the hierarchical data structure, and extract information requested by the query from the sub documents.
