Elasticsearch multi match nested fields

query. (Required, query object) Query you wish to run on nested objects in the path . If an object matches the search, the nested query returns the root parent document. You can search nested fields using dot notation that includes the complete path, such as obj1.name. Multi-level nesting is automatically supported, and detected, resulting in an inner nested query to automatically match the relevant nesting level, rather than root, if it exists within another nested query. bedini motor generator kitopen bo tangerang twitter

Response always returns an arrayedit.

Please take a look at the location field, we have a nested object consisting of fields type and coordinates. These meta-fields help Elasticsearch in identifying the geo shape and its actual data. 4.2. LineString
When using single index per document type, the number of shards increases which affects the performance of search. I wanted to use multi_match query on multiple fields, so each index has it's shard and for 3 indexes with roughly 16k documents the search is taking about 2.5 to 3 seconds, that's why trying to merge documents into a single index so that shards count decreases and the search could ...

Elasticsearch is an open source search and analytic engine based on Apache Lucene that allows users to store, search, analyze data in near real time. While Elasticsearch is designed for fast queries, the performance depends largely on the scenarios that apply to your application, the volume of data you are indexing, and the rate at which applications and users query your data.
Multi match with no fields specifiededit Starting with Elasticsearch 6.1.0+, it’s possible to send a Multi Match query without providing any fields.
