Let's say I have 5 shapefiles, and I want to use them as a single address locator via the ILocator interface. What would you recommend?
1) Merge the shapefiles into a single shapefile then convert to a feature class?
2) Merge multiple feature classes into a single feature class?
3) Get multiple locators and merge them into a single locator?
