The search radius has to be specified by the user. It is currently limited to a maximum of 30 arcsec. It depends mostly on the precision or quality of the coordinates (SIMBAD and VizieR catalogs), the resolution of the images from which the sources were extracted, source extent, and source crowding. Suggestions are: crowded field: 0.5 to 1.5 arcsec, 3 arcsec otherwise; uncertain coordinates (SIMBAD quality E or coordinates without reference): 5 to 30 arsec (risky!).
Some important notes on this object about identifications and objects associations. notes: According to Flesch (2013PASA...30....4F), the position of the quasar [VV2010] J074625.8+244901 in Veron-Cetty and Veron (2010A&A...518A..10V) is 3601" off, making it a duplicate with the object at position 07 46 25.8 +25 49 02.
