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...
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 ...

bool 查询是Elasticsearch中最强大的查询类型之一,它允许你组合多个查询子句,从而实现跨多个字段的复杂查询。例如,你可以使用bool 查询结合多个term 查询来实现对多个字段的精确匹配: json { "query": { "bool": { "must": [ { "term": { "field1": "value1" } }, { "term": { "field2": "value2...

You can also consider alternatives such as ElasticSearch. To get started with this sample, please register a new app with Algolia. Afterwards, create a new app and navigate to Indices, where we will create a new index called document_search. The document_search index After configuring your app...
