Apache Solr搜索：返回查询是字段一部分的结果(Apache Solr searching: return results where query is part of a field)

 我搜索“大括号”并希望返回3个结果（见帖子底部）。 但是我只得到结果，其中“brace”是一个单独的关键字而不是关键字的一部分。 我想指定一个权重，其中确切的单词具有最重要的权重，然后是较轻的权重，搜索字符串是另一个单词的一部分。  
 我试过了：  
title_search_global:"brace"^100  
title_search_global:*"brace"^100  
title_search_global:"*brace*"^100  
 
 但这些都不起作用。  
 查询：  
http://localhost:8983/solr/test/select/?indent=on&facet=true&wt=json&sort=clickcount%20desc&start=0&rows=9&fl=id,title&q=(title_search_global:(brace)%20OR%20title_search_global:%22brace%22^100))
 
 返回：

I search on "brace" and want 3 results returned (see bottom of post). However I only get the results where "brace" is a separate keyword and not part of a keyword. I want to assign a weight where the exact word has the heighest weight attributed to it, then a lighter weight to where the search string is part of another word. 
I tried:  
title_search_global:"brace"^100  
title_search_global:*"brace"^100  
title_search_global:"*brace*"^100  
 
But none of these work.

 唯一具有特殊意义的方法是main函数，它在您启动程序时自动调用。 但负载没有特别的意义。 它的目的是避免在构造对象时加载数据，以防它在任何地方传递（并且所有副本最终会反复加载数据）。  
 总之，没有。 它没有特别的意义。 你必须在某处调用它。 由于它是私有的，你应该检查你的构造函数。 它可能正在调用Load。 

The only method that has special significance is the main function, which gets called automatically when you start the program. Load however, has no special significance. Its purpose is to avoid the loading the data when constructing the object, just in case it gets passed around everywhere (and all the copies would end up loading the data over and over). 
In short, no. It has no special significance. You have to be calling it somewhere. Since it's private, you should check your constructor. It's probably calling Load.
