The default spellingsensitivity for geocoding request is 80. By specifying a higher value of spelling sensitivity in a GET_GEOCODE request such as in the sample given below or in GCSTYLE in the map configuration file, will cause ArcSDE to be a bit more sensitive on it's searching (and speed it up as well) because with a higher spelling sensitivity level, it will only search out exact street name matches, instead of include almost every street name that starts with a number.<GET_GEOCODE maxcandidates="20" minscore="50" spellingsensitivity="100"> <LAYER id="0"> </LAYER> <ADDRESS> <GCTAG id="STREET" value="37th Ave"/> <GCTAG id="CROSSSTREET" value="CAMPBELL"/> </ADDRESS> </GET_GEOCODE>
