Abstract
Embodiments described herein provide a system for facilitating efficient indexing in a database. The system can maintain a data table in the database. The data table includes a first column for structured data and a second column for unstructured text. A row of the data table can include a first piece of data in the first column and a second piece of data in the second column. During operation, the system performs word segmentation on the second piece of data to generate a first set of semantically meaningful word segments. The system then generates a set of index entries that corresponds to the row. A respective index entry includes an index generated from the first piece of data and a corresponding word segment of the first set of semantically meaningful word segments.
