Hi Fleming, There are examples in the test code: http://svn.apache.org/viewvc/hadoop/hbase/branches/0.20/src/contrib/indexed/src/test/org/apache/hadoop/hbase/regionserver/TestIdxRegion.java?view=markup
<http://svn.apache.org/viewvc/hadoop/hbase/branches/0.20/src/contrib/indexed/src/test/org/apache/hadoop/hbase/regionserver/TestIdxRegion.java?view=markup>Here's a snippet: > IdxScan idxScan = new IdxScan(); > idxScan.addFamily(Bytes.toBytes("family")); > idxScan.setExpression(Comparison.comparison(family, qualLong, > Comparison.Operator.GTE, Bytes.toBytes(50L))); > > You also need to provide a filter that (at least) matches your index expression hint. In your example and the one I've posted above the SingleColumnValueFilter would be fine... Could you elaborate a bit more on the results you are seeing? Is the scan returning more results than you expect? Is it not returning any results? Also, don't you need to specify the families/columns you want to return in the scan (see example code above)? I'm not 100% sure on that but I've always done it...
