Usage Notes

Enabling both the word position and element word position indexes will speed up query performance for many queries that use cts:json-property-scope-query. The position indexes enable MarkLogic Server to eliminate many false-positive results, which can reduce disk I/O and processing, thereby speeding the performance of many queries. The amount of benefit will vary depending on your data.
