             Summary: Support multi-column property indexes
                 Key: OAK-1871
                 URL: https://issues.apache.org/jira/browse/OAK-1871
             Project: Jackrabbit Oak
          Issue Type: Bug
          Components: query
            Reporter: Thomas Mueller


Currently, all property indexes are single-column. To speed up some use cases, the property
index should support multiple columns. Example use case: 

Property "size" with low cardinality (low number of distinct values, for example "S", "M",
"L", "XL"). Property "color" with low number of cardinality ("white", "black", "red",...).
The query condition is "where size = 'L' and color = 'white'". The number of matching nodes
is small.
