如何使用typesense实例搜索适配器在过滤器多边形中使用geo位置

Question

我用typesense创建了一个示例实例搜索js。

问题是当我搜索城市结果时，所有结果都用_geoloc和多边形进行过滤。。

我使用_geoloc字段来存储lat长，并在类型中使用浮点数数组。

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

_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",
    },
});

谢谢你帮助@ErJab

经过一番研究，我找到了一个新的解决方案，而且效果很好。

Typesense适配器更新了用于多边形搜索的代码。

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搜索。

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,
    }),
]);

从Typesense Instantsearch适配器的v2.1.0开始，您可以为此使用configure InstantSearch.js小部件，而不是将其传递到Typesense适配器。

就像这样：

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,
});
