如何强制执行完全匹配以获取最高优先级? [英] How to enforce an exact match to get the highest priority?
问题描述
我正在索引和搜索5个字段，它们以各种方式被标记/过滤.
但是，我希望在搜索时，如果输入的查询与字段1中的值匹配，它将是返回的最高结果.
我将如何定义:
I am indexing and searching 5 fields, which are tokenized/filtered in various ways.
BUT, I would like that when I search, if the query I entered matches a value in field 1, it will be the top result I get back.
How would I define:
- 领域
- 以100％匹配的方式使该字段具有优先级的查询
在我的模式中，我有一个字段
In my schema, I have the field
<field name="na_title" type="text_names" indexed="true" stored="false" required="true" />
text_names是:<fieldType name="text_names" class="solr.StrField" />
text_names is :<fieldType name="text_names" class="solr.StrField" />
我只有个条目，其中na_title ="somthing发生在这里".但是，当我搜索
text_names:somthing is going on here我得到很多结果.
只是指出这一点，该字段上没有用于查询和索引操作的分析器或过滤器.
I have ONLY one entry with na_title="somthing is going on here". But, when I search
text_names:somthing is going on here I get many results.
Just to point it out, there are no analyzers nor filters on that field, both for query and index actions.
推荐答案
您将需要对该字段建立两次索引-分析一次，然后一次不索引.然后，您可以提高未分析字段中的匹配项.
You'll need to index the field twice -- once analyzed and once not. Then you can boost the matches in the nonanalyzed fields over the others.
一种快捷方式可能是将所有这些字段都索引为字符串，并使用copyfield将它们作为文本复制到一个包罗万象的字段中.这样可以稍微简化查询并减少重复字段的数量.
A shortcut could be to index all those fields as strings and use copyfield to copy them as text into a catch-all field. That would simplify the query a little and decrease the number of duplicate fields.
