arcpy select by location search distance

# Description: Finds distance of each near point from each input point and outputs to a table. But I choose the target layer, the layer that I'm going to select from. Find Nearest requires two inputs: an input feature layer and a near feature layer. It can also be done by running the near analysis tool in ArcToolbox, using the area of interest and the infrastructure dataset as inputs. I'm trying to use a search cursor to iterate through a table and select the nearest centroids to the feature in the cursor, but when I try this instead of only selecting the centroids nearest the point in the cursor, it instead selects all of the centroids that distance from all of the points, then iterates to the next feature and selects all of them again. In the Select by Location window, select the options to query "2009EQ" "Within a Distance of" "bounds".
