This warning message means that something is wrong in the AEM instance where the /oak:index/damAssetLucene index isn't working. That causes the query above to do a traversal instead of using the damAssetLucene index.
Something is wrong with the /oak:index/damAssetLucene index. You would need to investigate the log files and search for "damAssetLucene" to find out the exact root cause.
A. Investigate the root cause
Search in the error.log and any other configured indexing logs for "damAssetLucene". Investigate on any ERROR or WARN level messages to see if they are the cause of the issue.
For example, in one customer's case, this was the cause of issue:
22.03.2017 12:46:45.205 *ERROR* [Thread-44] org.apache.jackrabbit.oak.plugins.index.lucene.IndexTracker Could not access the Lucene index at /oak:index/damAssetLucene java.io.FileNotFoundException: [/oak:index/damAssetLucene] segments_8o28
