Suggestions

Provide "Did you mean __?" or autocomplete functionality to your app's search form with CBElasticsearch

Suggestors are ElasticSearch's way of providing similar looking terms. They fall into two different use cases: "Did you mean...?" or spell check functionality and autocomplete functionality.

You can access the suggestions on the SearchResult component using the getSuggestions method.

Did you mean...?

cbElasticSearch can provide a spell-checked or "Did you mean...?" suggestions using either the suggestTerm or suggestPhrase methods.

• suggestTerm(string text, string name, string field = arguments.name, struct options = {}) - Adds a term suggestion to the query.

• suggestPhrase(string text, string name, string field = arguments.name, struct options = {}) - Adds a phrase suggestion to the query.

Term suggestions suggestors on a single word at a time, while phrase suggestors operate on an entire phrase. Any additional options shown on the website can be passed in as the options struct.

Term and phrase suggestors are usually added to an existing query. The results will appear in a suggest property on the SearchResult.

More information on how to optimize term and phrase suggestors can be found in the ElasticSearch documentation.

Autocomplete

cbElasticSearch can also provide autocomplete behavior using the suggestCompletion method. This adds a completion block to the suggest query.

• suggestCompletion(string text, string name, string field = arguments.name, struct options = {}) - Adds a completion suggestion to the query.

Completion suggestors can only operate against a mapping of type completion. This can be built either using the struct notation or the MappingBuilder#completion method.

Completion suggestors usually operate without a query. It is recommended you also only bring back the _source fields that you need. If you do not need any of the _source fields, you can setSource( false ) to not bring back _source at all.
