Represents an index. The index should use the data in the filter if possible to speed up reading.
org.apache.jackrabbit.oak.spi.query.QueryIndex
Represents an index. The index should use the data in the filter if possible to speed up reading.
The query engine will pick the index that returns the lowest cost for the given filter conditions.
The index should only use that part of the filter that speeds up data lookup. All other filter conditions should be ignored and not evaluated within this index, because the query engine will in any case evaluate the condition (and join condition), so that evaluating the conditions within the index would actually slow down processing. For example, an index on the property "lastName" should not try to evaluate any other restrictions than those on the property "lastName", even if the query contains other restrictions. For the query "where lastName = 'x' and firstName = 'y'", the query engine will set two filter conditions, one for "lastName" and another for "firstName". The index on "lastName" should not evaluate the condition on "firstName", even thought it will be set in the filter.
