Relevance ranking arranges your search results so that the retrieved records that are most likely to be relevant to your search request display first.

You can use Relevance Ranking Evaluator to test and experiment with relevance ranking strategies. It uses your own data and MDEX Engine to model how different strategies produce results.

The Relevance Ranking Evaluator can run multiple searches simultaneously, using different relevance ranking modules and other search parameters so you can compare the order and quality of returned results. It compares search results and their relevance ranking strategies side-by-side, highlighting the location of records in each strategy. Relevance Ranking Evaluator also provides performance metrics for each query that helps you evaluate the run-time performance in some of the more complex relevance ranking modules.
