ts_end range is not pushed indexer. This can heavily impact because Fetch involved.
| Issue | Resolution |
| A query plan was changed between Server releases. This meant the filter did not update the index when an OR clause pushed variable spans. | The OR clause has been modified to correct this issue. |
