使用 Elasticsearch 2 和 Rails 4,使用 elasticsearch-model gem
一切都很好,甚至地理点距离也在工作。但是,我一生都无法弄清楚如何使简单的布尔过滤器起作用。我有一个简单的布尔值“exclude_from_search_results”(如果为真),应该会导致从结果中过滤掉记录。
这是我在 rails 控制器中的查询(没有过滤器):
@response = Firm.search(
query: {
bool: {
should: [
{ multi_match: {
query: params[:search],
fields: ['name^10', 'address_1', 'address_2', 'address_3', 'address_4', 'address_5', 'address_6'],
operator: 'or'
}
}
]
}
},
aggs: {types: {terms: {field: 'firm_type'}}}
)
我已经在 bool 或 query 部分或外部添加了它,但我要么没有得到任何文档,要么得到所有文档。(9000 应该匹配)
例子:
@response = Firm.search(
query: {
bool: {
should: [
{ multi_match: {
query: params[:search],
fields: ['name^10', 'address_1', 'address_2', 'address_3', 'address_4', 'address_5', 'address_6'],
operator: 'or'
}
}
],
filter: {
term: {"exclude_from_search_results": "false"}
}
}
},
aggs: {types: {terms: {field: 'firm_type'}}}
)
我还尝试将过滤器子句放在不同的位置,但要么出错,要么没有结果。我究竟做错了什么??可能缺少一些简单的东西......
这是我的映射:
"mappings" : {
"firm" : {
"dynamic" : "false",
"properties" : {
"address_1" : {
"type" : "string",
"index_options" : "offsets",
"analyzer" : "english"
},
"address_2" : {
"type" : "string",
"index_options" : "offsets",
"analyzer" : "english"
},
"address_3" : {
"type" : "string",
"index_options" : "offsets",
"analyzer" : "english"
},
"address_4" : {
"type" : "string",
"index_options" : "offsets",
"analyzer" : "english"
},
"address_5" : {
"type" : "string",
"index_options" : "offsets",
"analyzer" : "english"
},
"address_6" : {
"type" : "string",
"index_options" : "offsets",
"analyzer" : "english"
},
"exlude_from_search_results" : {
"type" : "boolean"
},
"firm_type" : {
"type" : "string",
"index" : "not_analyzed"
},
"location" : {
"type" : "geo_point"
},
"name" : {
"type" : "string",
"index_options" : "offsets",
"analyzer" : "english"
}
任何指针都非常感谢...
