The ability to undo a QUAFLIFY keyword search and to restore the previous internal ID list.

An indexing option which stores index pointer as a bitmap, providing efficient indexing for “low cardinality” data. See also: Cardinality. Omnidex uses bitmap indexes as an option for low cardinality data.

Bitmap joins are characterized by having the “from” table and the “to” table as the same child, the purpose being to change which owner is current for the table. This step may be taken when joining between a parent and a child that are not already pre-joined.

AND (,), OR (+), and NOT (,-) operators used to combine keywords during an Omnidex retrieval.

A type of index optimized for sorted and partial key retrievals by on column or concatenation of columns, requiring left justification of data and case-sensitive matching.

The fundamental type of indexing on which relational databases are founded. Omnidex uses B-Trees internal for some of its indexes.
