When performing an intersection geocode of two different streets with similar names, I'm given many incorrect results with varying high scores. When I geocode intersections where the street names are not similar I get the expected single match with a score of 100. This ONLY happens when the street names have similar words.
"LEILA CT & LEILA LN" "SAINT CHARLES ST & E SAINT CHARLES ST" "FRANKLIN RD & FRANKLIN ST"
To describe in detail I'll explain further with the "LEILA CT & LEILA LN" intersection as an example.
This is a valid intersection and it should only produce one point of intersection. However, I get 22 different results. What appears to happen is the first result is given a 100 score and plots to the correct point. Then the next results are of all the intersections with the first road. They are listed as "LEILA CT & LEILA CT" (note that it is repeating the first road name but it plots at Leila CT & <OTHER ROAD>). Then the next results are all the intersections along the second road, also listing them strangely (ie "LEILA LN & LEILA LN"). Then finally, the last result is the reverse of what was searched, "LEILA LN & LEILA CT" and plots to the correct position. Essentially being a duplicate of the first but given the lowest overall score of 93.83.
I am able to reproduce this is multiple data sets. I'm using ArcDesktop 10.1 SP1.
