# How vLex Library Ranks Search Results

### Summary

vLex Library sorts your search results by **Relevance** by default to ensure the most important information appears at the top. This ranking is calculated by a smart algorithm that considers multiple factors beyond simple keyword matching.

### Why This is Important

Understanding how results are ranked builds confidence in your **vlex legal research**. It clarifies why certain documents appear first, assuring you that the ranking is based on legal authority and relevance, not just random keyword hits.

### Factors That Determine Result Ranking

Our relevance algorithm is a blend of several key factors:

* **Textual Ranking:** How closely the text of the document relates to your search terms.
* **Legal Ranking:** The authority of the source. For example, a Supreme Court decision will rank higher than a lower court decision.
* **Citation Frequency:** Documents that are cited more often by other authoritative sources are ranked higher.
* **Social Ranking:** The algorithm learns from how users interact with documents. Highly visited and utilized documents gain relevance.
* **Personal Ranking:** The system considers your followed **SmartTopics** and documents, giving a slight boost to content that matches your stated interests.
* **Editorial Ranking:** For very common searches, our legal editorial team may manually curate the top results to ensure quality.
