Example Embodiment
[0046] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.
[0047] The embodiment of the present invention discloses a method and system for implementing an inverted index based on string segmentation on SQL On HBase, which narrows the query range, and improves query efficiency by further precise query on the base table based on the reduced number of records; It does not rely on third-party components, and is completely based on the database's own architecture. It realizes the inverted index that is only available on traditional relational databases. It supports front fuzzy, middle fuzzy after fuzzy and front and back fuzzy queries, greatly improving fuzzy query The efficiency also makes the support for unstructured data better.
[0048] The invention solves the problem of creating an inverted index on the HBase table structure, and can facil...
