如何使用 typesense 即时搜索适配器在过滤器多边形内使用地理位置

Question

我用 typesense 创建了一个演示即时搜索 js。

问题是当我搜索城市时，所有结果都没有使用 _geoloc 和多边形进行过滤。

我使用 _geoloc 字段在 typesense 中存储带有 float 数组的经纬度。

{"name": "_geoloc", "type": "float[]" , "facet": true },

并且 _geoloc 在 Typesense instantSearch 适配器中传递 geoLocationField 参数。

const polygon = [
    42.01,-124.31,
    48.835509470063045,-124.40453125000005,
    45.01082951668149,-65.95726562500005,
    31.247243545293433,-81.06578125000004,
    25.924152577235226,-97.68234374999997,
    32.300311895879545,-117.54828125      
];

const typesenseInstantsearchAdapter = new TypesenseInstantSearchAdapter({
    server: {
        apiKey: "xyz",
        nodes: [{
            host: "localhost",
            port: "8108",
            protocol: "http",
        }, ],
        cacheSearchResultsForSeconds: 2 * 60,
    },
    insidePolygon: [polygon],
    geoLocationField: "_geoloc",
    additionalSearchParameters: {
        queryBy: "name",
    },
});

Answer 1

从 v2.1.0 of the Typesense Instantsearch adapter, you can use the configure InstantSearch.js 开始，这个小部件，而不是将其传递到 Typesense 适配器。

像这样：

const polygon = [
    42.01,-124.31,
    48.835509470063045,-124.40453125000005,
    45.01082951668149,-65.95726562500005,
    31.247243545293433,-81.06578125000004,
    25.924152577235226,-97.68234374999997,
    32.300311895879545,-117.54828125      
];

instantsearch.widgets.configure({
  insidePolygon: polygon,
});

感谢您帮助@ErJab

经过一些研究，我得到了一个新的解决方案，而且它运行良好。

Typesense 适配器更新了他们的多边形搜索代码。

https://github.com/typesense/typesense-instantsearch-adapter/blob/978af9577ef632003aa2de6b1761772d979377eb/src/SearchRequestAdapter.js#L167-L198

现在我们可以在多边形内部搜索了。

const polygon = [
    42.01,-124.31,
    48.835509470063045,-124.40453125000005,
    45.01082951668149,-65.95726562500005,
    31.247243545293433,-81.06578125000004,
    25.924152577235226,-97.68234374999997,
    32.300311895879545,-117.54828125      
];
const typesenseInstantsearchAdapter = new TypesenseInstantSearchAdapter({
    server: {
        apiKey: "xyz",
        nodes: [{
            host: "localhost",
            port: "8108",
            protocol: "http",
        }, ],
        cacheSearchResultsForSeconds: 2 * 60,
    },
    geoLocationField: "_geoloc",
    additionalSearchParameters: {
        queryBy: "name",
    },
});
const searchClient = typesenseInstantsearchAdapter.searchClient;

const search = instantsearch({
    searchClient,
    indexName: "airports",
});

search.addWidgets([
    searchBox({
        container: '#searchbox',
        placeholder: 'Search for products',
    }),
    configure({
        insidePolygon : polygon,
    }),
]);
