-#' With ambiguous user input, the returned results are chosen based on their matching score using [mo_matching_score()]. This matching score is based on four parameters:
-#' 
-#' 1. The prevalence \eqn{P} is categorised into group 1, 2 and 3 as stated above;

-#' 4. The [Levenshtein distance](https://en.wikipedia.org/wiki/Levenshtein_distance) \eqn{L} is the distance between the user input and all taxonomic full names, with the text length of the user input being the maximum distance. A modified version of the Levenshtein distance \eqn{L'} based on the text length of the full name \eqn{F} is calculated as:
-#' 
-#' \deqn{L' = 1 - \frac{0.5L}{F}}{L' = 1 - ((0.5 * L) / F)}
-#'   
-#' The final matching score \eqn{M} is calculated as:
