To enable Search Data Vault, you must create a search index for each table you want to include in the search. Each search index contains a list of columns you specify in Enterprise Data Manager. When you search Data Vault with a keyword, the search engine looks for the keyword in indexed columns. If the keyword is in an indexed column, the corresponding record appears in the search results. If the keyword is not in an indexed column, the record does not appear in the results even if the record contains the keyword in another column.
