| <p>Search queries can be executed using two different strategies. The default strategy is determined by the |
| "druid.query.search.searchStrategy" runtime property on the Broker. This can be overridden using "searchStrategy" in the |
| query context. If neither the context field nor the property is set, the "useIndexes" strategy will be used.</p> |
| <ul> |
| <li><p>"useIndexes" strategy, the default, first categorizes search dimensions into two groups according to their support for |
| bitmap indexes. And then, it applies index-only and cursor-based execution plans to the group of dimensions supporting |
| bitmaps and others, respectively. The index-only plan uses only indexes for search query processing. For each dimension, |
| it reads the bitmap index for each dimension value, evaluates the search predicate, and finally checks the time interval |
| and filter predicates. For the cursor-based execution plan, please refer to the "cursorOnly" strategy. The index-only |
| plan shows low performance for the search dimensions of large cardinality which means most values of search dimensions |
| are unique.</p></li> |
| <li><p>"cursorOnly" strategy generates a cursor-based execution plan. This plan creates a cursor which reads a row from a |
| queryableIndexSegment, and then evaluates search predicates. If some filters support bitmap indexes, the cursor can read |
| only the rows which satisfy those filters, thereby saving I/O cost. However, it might be slow with filters of low selectivity.</p></li> |
| <li><p>"auto" strategy uses a cost-based planner for choosing an optimal search strategy. It estimates the cost of index-only |
| and cursor-based execution plans, and chooses the optimal one. Currently, it is not enabled by default due to the overhead |
| of cost estimation.</p></li> |
| </ul> |
