Solr 3.3.0 - 增加实地搜索量——加强外地优先事项
原标题：Solr 3.3.0 - Increase field weight in search - boost field priority

I m Indexing with solr 3.3.0 these docs:

    <copyField source="artist" dest="artist_ex" />

</fields>

你们可以看到,我是否在寻找一个排气器时回收所有的docs(Im使用固体)。 Edge a. 指数化工厂;我的成就是利用这一逻辑整理出文件:

  1. title_ex
  2. title
  3. keywords_ex
  4. keywords
  5. owner_ex
  6. artist_ex
  7. owner
  8. artist

我尝试了“^”的 l子和 dis子,但答复清单是我所说的。

http:// localhost:8080/solr33a/core0/select?q=abc&defType=edismax&qf=title_ex^10%20 entitled^8.0%20keywords_ex^6%20keywords^20 Owner_ex^1.2%20artist_ex^0.820 Owner^ 20art^0.2&fl=

结果:

As you want to search across multiple fields with variable weightage, configure your request handler to use edismax query parser.
dismax allows you to search across fields and add weights to each field.

Example title match has weight 1, while matches on author 0.8, so that document having title matches would appear at the top.

<requestHandler name="search" class="solr.SearchHandler" default="true">
 <lst name="defaults">
   <str name="echoParams">explicit</str>
   <str name="defType">edismax</str>
   <str name="qf">
      title^1 author^0.8
   </str>
   <str name="q.alt">*:*</str>
   <str name="rows">10</str>
   <str name="fl">*,score</str>
 </lst>
</requestHandler>
