Question

如何根据给定值对我的algolia记录进行排名？根据用户的ip位置，该值是动态的。

我希望SC州首先显示在列表中，我该怎么做？

例如我有记录

[
 {
   "category":"Emergency Department",
   "address": {"state": "SC"}
   ......
 },
 {
   "category":"Emergency Department",
   "address": {"state": "NC"}
   ......
 }, 
 {
   "category":"Emergency Department",
   "address": {"state": "NC"},
   ......
 }, 
 {
   "category":"Radiology",
   "address": {"state": "WV"}
   ......
 }, 
 {
   "category":"PROVIDENCE HOSPITAL",
   "address": {"state": "TN"}
   ......
 }, 
 {
   "category":"PROVIDENCE HOSPITAL",
   "address": {"state": "TN"}
   ......
 }, 
]

我写了这样的搜索代码

algoliaIndex.search({
   query: 'Emergency Department' +' '+ 'SC',
 }, function(err, hits) {
  console.log(hits.hits);
});

我的索引设置

[
 'searchableAttributes' => [
  'general_name',
  'name',
  'category',
  'address.city',
  'address.state',
  'address.zip_code',
  ],
 'customRanking' => [
   "desc(address.state)",
   "desc(general_name)"
  ],
]

您可以使用地理搜索功能根据用户的位置对结果进行排序。以下是实施该指南的指南：https://www.algolia.com/doc/guides/geo-search/geo-search-overview/#filter-and-sort-around-a-location

API允许您直接提供IP，它将自动转换为相应的坐标：https://www.algolia.com/doc/guides/geo-search/geo-search-overview/#by-looking-at-the-ip-address

要实现它，您需要将address.state字段转换为lat / lng坐标以使其正常工作。您可以查看此SO线程以查找数据库：Latitude and Longitude based on Zip Code
