See into your data and find answers that matter with enterprise solutions designed to help you build, observe, and protect. Try Elasticsearch free today. Without knowing more about your system, I suspect it is the IDF that is causing the mismatch. The IDF is calculated per shard, so if when your documents come from different shards, the scores can be different. Try using a distributed search type (dfs\_query\_then\_fetch) to see if the issue still persists: > **[Elasticsearch Platform — Find real-time answers at scale](https://www.elastic.co)** > > Power insights and outcomes with the Elasticsearch Platform and AI.

As predicted, your IDF values differ. Shard 1 has fewer documents than shard 4 with that term make the shard 1 documents more relevant. You can change the search type as described above. { "value": 6.8087983, "description": "idf(docFreq=86, maxDocs=28990)" }, { "value": 6.7636743, "description": "idf(docFreq=90, maxDocs=28985)" }, --
