Elasticsearch Abfragen

Elasticsearch Query DSL für komplexe Suche.

Match¶

GET /articles/_search
{
  "query": {
    "match": {
      "title": "elasticsearch tutorial"
    }
  }
}

Bool¶

{
  "query": {
    "bool": {
      "must": [{"match": {"content": "kubernetes"}}],
      "filter": [
        {"term": {"tags": "devops"}},
        {"range": {"published_at": {"gte": "2024-01-01"}}}
      ]
    }
  }
}

Aggregationen¶

{
  "size": 0,
  "aggs": {
    "by_tag": {"terms": {"field": "tags", "size": 20}},
    "avg_views": {"avg": {"field": "views"}}
  }
}

Query DSL = Leistungsstark¶

Bool-Abfragen + Aggregationen decken die meisten Anforderungen ab.
