The system may provision empty positions in posting lists to enable in-place updating, without having to rebuild the posting list or append updates to the end of the posting list. For example, a system comprises at least one processor and memory storing an index that includes at least one posting list that maps a term to a set of the documents. The posting list includes an ordered list of documents and has a plurality of open positions within the ordered list. The memory also stores instructions that, when executed by the at least one processor, cause the system to locate an open position of the plurality of open positions for a new document and to insert the new document into the at least one posting list using the open position."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"In-place updates for inverted indices","description":"Implementations provide an indexing system with near-instant updates to an inverted index while maintaining techniques for query optimization.
