Elasticsearch Search API - Rich Text 1

Elasticsearch Search API - BG Wrapper

Once you’ve ingested your content into Elasticsearch, the querying fun begins. Elasticsearch provides the querying capabilities that your applications demand, from a simple exact match on a single field to sophisticated multi-clause queries that span multiple fields, combining user input with other factors such as user preferences, location, and search context.

Let’s take a look at the basics of searching an Elasticseach collection, where we have a collection of customers names, like these:

A simple match query on first_name would be crafted in this manner:

Using Elasticsearch aggregations, the counts of each “type” of a matching customer can be incorporated into our search request response, providing the ability to display facets (also called “guided navigation”). Here is a more sophisticated search request that searches both first and last name fields, ranking matches on last name higher than first name, along with aggregation counts of customer types:

The response to this query would look like this:

Multi-index searching can be achieved where multiple collections are searched as if they were a single unified index. When a comma-separated list (or 

 for every user collection) is specified for the collection to be searched, all indicated collections are searched, and combined results are returned. This feature allows collections to be architected for independent or combined searching, such as separate collections of current customers and past customers, or separate collections per time period that can be queried together or independently. 

In conclusion, Elasticsearch offers state-of-the-art search and analytics capabilities behind a developer-friendly interface. Elasticsearch scales to handle enormous amounts of data. The most demanding applications in the world today are comfortably powered by Elasticsearch.
