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.

vLex Library uses a multi-factor algorithm to determine the most relevant results.
