== Search API
|
|
|
|
The search API is very similar to the
|
|
// {javaclient}/java-search.html[]
|
|
Java search API. The Groovy
|
|
extension allows to provide the search source to execute as a `Closure`
|
|
including the query itself (similar to GORM criteria builder):
|
|
|
|
[source,groovy]
|
|
--------------------------------------------------
|
|
def search = node.client.search {
|
|
indices "test"
|
|
types "_doc"
|
|
source {
|
|
query {
|
|
term(test: "value")
|
|
}
|
|
}
|
|
}
|
|
|
|
search.response.hits.each {SearchHit hit ->
|
|
println "Got hit $hit.id from $hit.index/$hit.type"
|
|
}
|
|
--------------------------------------------------
|
|
|
|
It can also be executed using the "Java API" while still using a closure
|
|
for the query:
|
|
|
|
[source,groovy]
|
|
--------------------------------------------------
|
|
def search = node.client.prepareSearch("test").setQuery({
|
|
term(test: "value")
|
|
}).gexecute();
|
|
|
|
search.response.hits.each {SearchHit hit ->
|
|
println "Got hit $hit.id from $hit.index/$hit.type"
|
|
}
|
|
--------------------------------------------------
|
|
|
|
The format of the search `Closure` follows the same JSON syntax as the
|
|
{ref}/search-search.html[Search API] request.
