Solr搜索响应顺序:基于令牌位置

Question

我想要按匹配代币位置排序的搜索结果文档

示例：我有以下文档：

1. indian institute of technology
2. cultural arts institute
3. institute of Management
4. institute of Arts

search query : ins*
localhost:6983/solr/ts/select?fl=name&indent=true&q.op=OR&q=name%3Ains*
Expected response : 

3. institute of Management  ----> (institute position ->1)
4. institute of Arts        -----> (institute position ->1)
1. indian institute of technology --> (institute position ->2)
2. cultural arts institute   ------> (institute position ->3)

我在autoSugest中尝试过，但它不适合我的用例，使用autoSugest的缺点是：无法对多个值和字段运行筛选器，无法在响应时返回多个字段

可能有一种更简单的方法来实现您想要的，但这肯定可以使用自定义记分器来处理。这个博客解释了创建自定义记分器的过程，并概述了其他角度，通过这些角度你可以解决这个问题
