Abstract
A computing system receives as inputs data records stored in a database. The computing parses the data records into file pairs that each include a keyword file and record ID file and merge file pairs into a keyword file and record ID file, where the keyword file includes keywords in sorted order, and where the record ID file includes a list of record IDs for keywords in the keyword file. The computing system further creates an offset file which stores offset values for starting addresses of record ID lists in the record ID file, and generates an index of keywords by assigning unique identifiers to keywords in the keyword file. The computing system also provides a query interface that allows the database's data records to be searched using the generated index of keywords.
