A processing device performs a search query to produce a search result set having entries having data items. Each data item has an ordinal position. A table, having rows and columns, is displayed in a graphical user interface. Each data item of a particular entry appears in a respective column of the same row of the table. Each column corresponds to the ordinal position of its respective data item. User input is received designating, for each respective column, a field name and an entity definition component type to which the respective column pertains, and stores for each data item of the particular entry an element value of an entity definition. The element has the element name designated for the respective column in which the data item appeared, and is associated with an entity definition component having the type designated for the respective column in which the data item appeared.
