| + | * a field, or column, that is used to select records from a data set, providing fast access to rows. Keys are typically indexed, uniquely identify parent rows, and provide a correlation for joining tables and maintaining data integrity across tables. See also Native keys and OMNIDEX indexes. | ||
| - | key | + | ==== Key options ==== |
| + | * enhancements to OMNIDEX keys that are specified during installation to enable certain retrieval features (like Grouping) or update features (like Batch indexing). | ||

Keys are typically indexed, uniquely identify parent rows, and provide a correlation for joining tables and maintaining data integrity across tables.

| + | * A word or number that is indexed for an MDK Index | ||
| + | * An individual word or value in an MDK Index column delimited by spaces and punctuation. For example, if an MDK Index column contains "Kraft-Ebbing's Bait and Tackle" the words "KRAFT", "EBBING", "EBBING'S", "BAIT", and "TACKLE" are indexed as keywords. | ||
| - | * enhancements to OMNIDEX keys that are specified during installation to enable certain retrieval features (like Grouping) or update features (like Batch indexing). | + | ==== Keyword access ==== |
| + | * the ability to find rows based on the words contained in a given field, regardless of the order in which the words appear. This is a primary feature of OMNIDEX indexes. | ||

| + | * Indexes composed of a word or words from a specified field in a database row. Renamed to MDK Indexes. | ||
| - | * retrieval by an OMNIDEX or TurboIMAGE key field. | + | ==== Keyword lookup ==== |
| + | * to look up data by words embedded within strings of text. | ||
| - | keyword | + | ==== Keyword retrieval ==== |
| - | + | * refers to an OMNIDEX retrieval of record identifiers by any keyword value or combination of keyword values against an MDK Index. | |
