+
+Sourcegraph Enterprise users can get more personalized and better-ranked search results in the search bar for their codebases. With this experience enabled, you can get intelligently ranked results for your full query for keyword searches like "data router". You also get results boosted from repositories you’ve recently contributed to, making it easier to find the code you care about faster.
+
+The personalized search ranking works best if you have large codebases, especially for new users who may otherwise get overwhelmed by results from unfamiliar or irrelevant repositories.
+
+It is enabled by default, but you can disable it from your settings via:
+
+```json
+experimentalFeatures: {
+  boostRelevantRepositories: false
+}
+```
+
+Here is an example of search results with personalized search ranking enabled:
+

+
+As you can see, the results are now ranked based on their relevance to the query, and the results from repositories you've recently contributed to are boosted.
