@ -12,43 +12,32 @@ Here is an example on how to create the aggregation request:
[source,java]
--------------------------------------------------
ScriptedMetricAggregationBuilder aggregation = AggregationBuilders
.scriptedMetric("agg")
.initScript(new Script("_agg['heights'] = []"))
.mapScript(new Script("if (doc['gender'].value == \"male\") " +
"{ _agg.heights.add(doc['height'].value) } " +
"else " +
"{ _agg.heights.add(-1 * doc['height'].value) }"));
.scriptedMetric("agg")
.initScript(new Script("params._agg.heights = []"))
.mapScript(new Script("params._agg.heights.add(doc.gender.value == 'male' ? doc.height.value : -1.0 * doc.height.value)"));
--------------------------------------------------
You can also specify a `combine` script which will be executed on each shard:
[source,java]
--------------------------------------------------
ScriptedMetricAggregationBuilder aggregation =
AggregationBuilders
.scriptedMetric("agg")
.initScript(new Script("_agg['heights'] = []"))
.mapScript(new Script("if (doc['gender'].value == \"male\") " +
"{ _agg.heights.add(doc['height'].value) } " +
"else " +
"{ _agg.heights.add(-1 * doc['height'].value) }"))
.combineScript(new Script("heights_sum = 0; for (t in _agg.heights) { heights_sum += t }; return heights_sum"));
ScriptedMetricAggregationBuilder aggregation = AggregationBuilders
.scriptedMetric("agg")
.initScript(new Script("params._agg.heights = []"))
.mapScript(new Script("params._agg.heights.add(doc.gender.value == 'male' ? doc.height.value : -1.0 * doc.height.value)"))
.combineScript(new Script("double heights_sum = 0.0; for (t in params._agg.heights) { heights_sum += t } return heights_sum"));
--------------------------------------------------
You can also specify a `reduce` script which will be executed on the node which gets the request:
[source,java]
--------------------------------------------------
ScriptedMetricAggregationBuilder aggregation =
AggregationBuilders
.scriptedMetric("agg")
.initScript(new Script("_agg['heights'] = []"))
.mapScript(new Script("if (doc['gender'].value == \"male\") " +
"{ _agg.heights.add(doc['height'].value) } " +
"else " +
"{ _agg.heights.add(-1 * doc['height'].value) }"))
.combineScript(new Script("heights_sum = 0; for (t in _agg.heights) { heights_sum += t }; return heights_sum"))
.reduceScript(new Script("heights_sum = 0; for (a in _aggs) { heights_sum += a }; return heights_sum"));
ScriptedMetricAggregationBuilder aggregation = AggregationBuilders
.scriptedMetric("agg")
.initScript(new Script("params._agg.heights = []"))
.mapScript(new Script("params._agg.heights.add(doc.gender.value == 'male' ? doc.height.value : -1.0 * doc.height.value)"))
.combineScript(new Script("double heights_sum = 0.0; for (t in params._agg.heights) { heights_sum += t } return heights_sum"))
.reduceScript(new Script("double heights_sum = 0.0; for (a in params._aggs) { heights_sum += a } return heights_sum"));
