Method A: Yummy GUI goodness
Download this application and run it. It's a wrapper for method B—all you have to do is double-click on it. It'll exit immediately; Spotlight will reimport your logs in the background.
Method B: The manual way
Run the following command from Terminal to force Spotlight to reimport all logs:
mdimport -r "/Applications/Adium.app/Contents/Library/Spotlight/AdiumSpotlightImporter.mdimporter"
If Adium is installed somewhere besides /Applications, change the path accordingly.
