# Description The Dense Vector Search page in the Solr Ref Guide currently has a section titled `Usage in Re-Ranking Query`. However, it only contains a single example of re-ranking with the KNN query parser which has an important caveat that this initiates a second pass full KNN query. This PR adds documentation for the more efficient re-ranking feature that rerank subsets of documents by direct vector comparisons with the [vectorSimilarity Function](https://solr.apache.org/guide/solr/latest/query-guide/function-queries.html#vectorsimilarity-function) , with some notes about motivations and tradeoffs. # Solution - Moves indentation level of `Usage in Re-Ranking Query` in Dense Vector Search ref guide - Adds examples of how to use `{!func}vectorSimilarity` in a re-rank query - Adds note about reranking with Dense Vector Fields in Query Re-Ranking page ## Before <img width="1486" height="1066" alt="solr_dense_vector_ref_guide_before" src="https://github.com/user-attachments/assets/edee7996-3eac-4117-833b-23597ec468ec"; /> ## After <img width="1490" height="1119" alt="solr_dense_vector_ref_guide_changes" src="https://github.com/user-attachments/assets/3284b706-272d-46cb-ad65-e3ebf00f861f"; /> # Checklist Please review the following and check all that apply: - [X] I have reviewed the guidelines for [How to Contribute](https://github.com/apache/solr/blob/main/CONTRIBUTING.md) and my code conforms to the standards described there to the best of my ability. - [ ] I have created a Jira issue and added the issue ID to my pull request title. - [X] I have given Solr maintainers [access](https://help.github.com/en/articles/allowing-changes-to-a-pull-request-branch-created-from-a-fork) to contribute to my PR branch.
