String and sub-string searching using inverted indexes
摘要:
Inverted indexes for terms and for term separators are separately provided to minimize data redundancy. Search queries are parsed to identify terms and term separators, if any, and the corresponding inverted indexes are searched for responsive documents. Related apparatus, systems, techniques and articles are also described.
