	A typographical matching algorithm. You specify (on a scale from 1 to 4, with 1 being the tightest) the degree of similarity between data being matched. This scale is then used as a weight which is adjusted on the length of the strings being. Because the algorithm creates a 2D array to determine the distance between two strings, results will be more accurate than Fast Near at expense of throughput.		:A typographical matching algorithm.

==Accurate Near==
===Specifics===
Accurate Near is a Melissa Data Algorithm largely based on the Levenshtein Distance Algorithm.
*https://en.wikipedia.org/wiki/Levenshtein_distance

===Summary===
A typographical matching algorithm. You specify (on a scale from 1 to 4, with 1 being the tightest) the degree of similarity between data being matched. This scale is then used as a weight which is adjusted on the length of the strings being. Because the algorithm creates a 2D array to determine the distance between two strings, results will be more accurate than Fast Near at expense of throughput.

===Returns===
Boolean ‘match’ if the normalized distance between two strings is less than the configured scale, where distance is defined as the count of the number of incorrect characters, insertions and deletions.

This works best in matching words that don't match because of a few typographical errors and where the accuracy in duplicates caught outweighs performance concerns.

===Do Not Use With===
