在 Elasticsearch Percolate API 中过滤执行的查询

Question

我有这个代码：

#!/bin/bash

# Deletes, then creates the collection "foo".
curl -s -XDELETE localhost:9200/foo > /dev/null
curl -s -XPUT localhost:9200/foo > /dev/null

# Creates two percolators called "barbaz1" and "barbaz2" with different
# values in the "plugh" field.
curl -XPUT localhost:9200/_percolator/foo/barbaz1 -d '{
    "plugh": "xyzzy",
    "query": {
        "term": {
            "bar": "baz"
        }
    }
}'
echo ""

curl -XPUT localhost:9200/_percolator/foo/barbaz2 -d '{
    "plugh": "waldo",
    "query": {
        "term": {
            "bar": "baz"
        }
    }
}'
echo ""

# First filters out all queries whose "plugh" field is not "waldo", then
# tries to match those. Does NOT work as expected!
curl -XGET localhost:9200/foo/qux/_percolate -d '{
    "doc": {
        "bar": "baz"
    },
    "query": {
        "term": {
            "plugh": "waldo"
        }
    }
}'
echo ""

# Deletes the created percolators.
curl -s -XDELETE localhost:9200/_percolator/foo/barbaz1 > /dev/null
curl -s -XDELETE localhost:9200/_percolator/foo/barbaz2 > /dev/null

这将创建两个名为 barbaz1 和 barbaz2 的过滤器，然后针对它们运行一个文档。我期望看到的是只有 barbaz2 匹配，而我得到的是：

{"ok":true,"_index":"_percolator","_type":"foo","_id":"barbaz1","_version":1}
{"ok":true,"_index":"_percolator","_type":"foo","_id":"barbaz2","_version":1}
{"ok":true,"matches":[]}

我做错了什么？

Answer 1

这不起作用，因为您在为过滤器编制索引后过早询问 _percolate。

如果您在渗透之前在_percolator 索引上添加refresh，它将起作用：

curl -XPOST 'http://localhost:9200/_percolator/_refresh'
