Example: simple full-text search
Consider the following ElasticsearchQuery:
{
"$query.query_string.query": "{{myPlaceholder}}",
"$size": "40",
"name": "Quick Search",
}
The query
parameter implements a very simple Query String, allowing intuitive fulltext search.
In order to execute the query this AND that OR thus
, the Trigger to the ElasticsearchQuery should fill in the search
parameter for the template:
{
"$params.myPlaceholder": "this AND that OR thus"
}
