The weighing factors between house number and additional letter
Daniel Schürmann
If no house number and no additional letter is provided, a random address in the given street is selected (qscore = 0).
If only an additional letter but no house number is given and the letter is unique, returns the corresponding record (qscore = 0.05). Otherwise returns a random one as mentioned above (qscore = 0).
If no additional letter, but house number is provided and the maximum distance to
a valid house number is 4, return the closest match as calculated by
l1score (qscore is the result of l1score). Otherwise a random record
is returned (qscore = 0).
If additional letter and house number are available and the house number distance is smaller then 4, calculates the l1scores of the house number distance and addional letters distance and selects the best match (qscore is the sum of both weighted l1scores). Otherwise a random record is selected (qscore = 0).
