问题：
如何在弹性搜索中避免重复无痛脚本
梁丘缪文
我有一个弹性查询脚本，用于使用我给出的参数计算地面距离，我必须在多个查询中使用它。是否有一种方法可以避免这种重复，例如，有一种计算全局变量并在所有脚本中使用它的方法。在本例中，我希望计算＜code＞距离

您应该使用存储的脚本，以便您可以通过id引用它：
POST _scripts/distance-script
{
"script": {
"lang": "painless",
"source":"def a=doc['id'].getValue();if (!params.containsKey(a.toString())) {return false;}double distance=params[a.toString()];return distance <= doc['maxDeliveryRadius'].getValue()"
}
}
然后，您可以在查询中引用上述脚本：
{
"query": {
"bool": {
"filter": [
{
"script": {
"script": {
"lang": "painless",
"params": { ... },
"id": "distance-script"
}
}
},
{
"script": {
"script": {
"lang": "painless",
"params": { ... },
"id": "distance-script"
}
}
}
]
}
}
}

我认为我们可以用不同的方式解决这个问题。在＜code＞bool/filter＜code＞中有两个脚本查询，这意味着和。此外，两个脚本中的参数相同。因此，您可以将这两个脚本组合起来，只使用一个脚本，如下所示：
POST _scripts/distance-script
{
"script": {
"lang": "painless",
"source":"""
def a = doc.id.value.toString();
if (!params.containsKey(a) {
return false;
}
double distance = params[a];
return distance <= doc.maxClassDeliveryDistance.value && distance >= params['minDistance'] && distance <= doc.maxDeliveryRadius.value;
"""
}
}
