根据Solr中多值字段的有效负载为得分加分 [英] Adding Boost to Score According to Payload of Multivalued Field at Solr

问题描述

这是我的情况；

我的架构中有一个名为elmo_field的字段.我希望elmo_field应该具有有效值.即

I have a field at my schema named elmo_field. I want that elmo_field should have payloaded values. i.e.

dorothy|0.46  sesame|0.37  big bird|0.19 bird|0.22

当用户搜索关键字(即dorothy)时，我想在常规得分上添加0.46.如果用户搜索big bird，则应添加0.19，如果用户搜索bird，则应添加0.22(添加有效载荷-或添加有效载荷*归一化系数).

When a user searches for a keyword i.e. dorothy I want to add 0.46 to usual score. If user searches for big bird, 0.19 should be added and if user searches for bird, 0.22 should be added (payloads are added - or payloads * normalize coefficient will be added).

我的意思是我将在Solr模式的其他字段中搜索索引.而且我将同时在elmo_field进行另一次搜索(这是一个完全匹配的搜索)，如果匹配，我将增加有效载荷的分数.

I mean I will make a search on my index at my other fields of solr schema. And I will make another search (this one is an exact match search) at elmo_field at same time and if matches something I will increase score with payloads.

有什么想法吗?

推荐答案

我已经实现了自定义相似性包装器.对于平常的事情，我使用了DefaultSimilarity.如果一个字段是有效字段，则使用由我实现的另一个相似性.该相似性类只是忽略有效负载值.我还实现了一个查询解析器，它是edismax的自定义版本.通过这种方法，我可以将有效负载值添加到文档分数中.

I've implemented a custom similarity wrapper. For usual things I've used DefaultSimilarity. If a field is a payloaded field another similarity that is implemented by me is used. That similarity class just ignores payload value. I've also implemented a query parser that is a customized version of edismax. With that approach I could add payload value into the document score.
