System and method for an index search engine

A method for searching an index field value, comprising:

• dividing a first non-volatile memory into a set of partitions;
• writing and storing the index field value to a search array file stored in one of the partitions, wherein the field index value and associated data values form a search array record of the search file;
• and
• indexing the index field value in an index structure in a second non-volatile memory,
• wherein:
• the index structure includes a four-memory level configuration;
• each memory level has a specified memory length;
• an entry in each memory level of first three levels contains a value pointing to a starting address of immediate next memory level;
• an entry in fourth memory level contains the indexed field value.
