node.js - Node JS Elasticsearch 结果改进

Question

使用与累计相关的 Elasticsearch 时出现问题，
示例数据

{
        "id": 2,
        "keyword": "Gas",
        "content": "{\"detail_name\":\"Gas\",\"detail_slug\":\"gas\",\"category_name\":\"Cooking\",\"category_slug\":\"cooking\",\"subcategory_name\":\"Cooktops\",\"subcategory_slug\":\"cooktops\",\"type\":\"1\"}"
    },
    {
        "id": 4,
        "keyword": "Gas: Downdraft",
        "content": "{\"detail_name\":\"Gas: Downdraft\",\"detail_slug\":\"gas-downdraft\",\"category_name\":\"Cooking\",\"category_slug\":\"cooking\",\"subcategory_name\":\"Cooktops\",\"subcategory_slug\":\"cooktops\",\"type\":\"1\"}"
    },
{
        "id": 86,
        "keyword": "Casement / Slider A / C Air Conditioner",
        "content": "{\"detail_name\":\"Casement \/ Slider A \/ C Air Conditioner\",\"detail_slug\":\"casement-slider-a-c-air-conditioner\",\"category_name\":\"Air Conditioning\",\"category_slug\":\"air-conditioning\",\"subcategory_name\":\"Air Conditioners\",\"subcategory_slug\":\"air-conditioners\",\"type\":\"1\"}"
    },
    {
        "id": 91,
        "keyword": "0 - 30 Pint Dehumidifier",
        "content": "{\"detail_name\":\"0 - 30 Pint Dehumidifier\",\"detail_slug\":\"0-30-pint-dehumidifier\",\"category_name\":\"Air Conditioning\",\"category_slug\":\"air-conditioning\",\"subcategory_name\":\"Dehumidifiers\",\"subcategory_slug\":\"dehumidifiers\",\"type\":\"1\"}"
    }

这是我的代码

client.search({
        index: 'search_index',
        size: 4,
        body: {
        sort: [{ "id": { "order": "asc" } }],
          query: {
            fuzzy: {
                keyword: {
                  value:  req.query.q,
                    "fuzziness": "1",
                    "max_expansions": 50,
                    "prefix_length": 0,
                    // "rewrite": "constant_score"
                }
            }
          }
        }
      }, (err, result) => {})

因此，当我输入关键字“g”或“Downdraft Gas”时，我想显示“Gas”或“Gas:Downdraft”
有没有我需要进一步改进的代码？
谢谢

这些确实帮助我改善了搜索查询。
永远不要使用模糊
在这种情况下，模糊查询将无济于事。文档引用:“返回包含与搜索词相似的词的文档，以Levenshtein编辑距离来衡量。编辑距离是将一个词转换为另一个词所需的一个字符更改的数量。”因此，如果您搜索“模糊度为1的“gas”会得到“has”，“gap”等结果。
