#' 3. The level of uncertainty \eqn{U} needed to get to the result, as stated above (1 to 3);
#' 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' = F - \frac{0.5 \times L}{F}}{L' = F - (0.5 * L) / F}
#' \deqn{L' = F - \frac{0.5L}{F}}{L' = (F - 0.5L) / F}
#'
#' The final matching score \eqn{M} is calculated as:
#' \deqn{M = L' \times \frac{1}{P \times K} * \frac{1}{U}}{M = L' * (1 / (P * K)) * (1 / U)}
#' \deqn{M = L' \times \frac{1}{P K U} = \frac{F - 0.5L}{F P K U}}{M = L' * (1 / (P * K * U)) = (F - 0.5L) / (F * P * K * U)}
#'
#' All matches are sorted descending on their matching score and for all user input values, the top match will be returned.
