Abstract
A database management system and method provides access to a data table having structured data and unstructured data. A user interface allows a user to issue instructions to the database management system such as to build an index based on the structured and unstructured data and to search the data table. An indexing logic generates an index structure by combining the structured and unstructured data. With this index structure, a single query can contain search conditions from both the structured data and the unstructured data. In this manner, efficiency for searching the data table for combined structured and unstructured conditions is improved.
