Elasticsearch 会在倒排索引中查找包括某 term 的所有文档,然后构造一个 bitset 。在我们的例子中,倒排索引表如下: 当term查询匹配标记search时,它直接在倒排索引中找到记录并获取相关的文档 ID,如倒排索引所示,这里文档 1 和文档 2 均包含该标记,所以两个文档会同时作为结果返回。 由于倒排索引表自身的特性,整个字...
在Elasticsearch中,terms查询用于精确匹配单个字段中的多个值。当尝试在terms查询中指定多个字段时,会抛出"[terms] query does not support multiple fields"的错误,这是因为terms查询的设计初衷是针对单个字段进行高效检索,而不是跨多个字段进行匹配。 可能的解决方案或替代查询方法 使用bool查询: bool查询是Elasticsearch...

What you're trying to do is form a compound query from two queries, where both queries must be satisfied by a document in order for it to be considered a match.Aboolquery is used to combine queries in this manner, using themustclause to specify both queries must be satisfied. Here's ...
Additionally, some usages of saved-objects have a significant impact on the performance and storage requirements of both Elasticsearch and Kibana. In these situations, when a saved-object is copied the copy itself will consume as many resources as the original saved-object. An example of this is...
