Solr dismax查询
我正在尝试创建一个功能，允许通过此公式sum（weight1 *文本相关性得分，weight2 *价格）显示搜索结果。 weight1 和 weight2 是可以更改以影响搜索结果的数值。
我将以下查询参数发送到 Solr 实例进行搜索。
q=red
defType=dismax
qf=10^name+2^price
我的理解是，当使用 dismax 时，Solr/Lucene 会在 qf 参数中指定的所有字段中查找搜索文本。
目前，我的搜索结果与 qf 不包含价格时得到的结果类似。我认为这是因为价格是数字字段并且没有文本匹配。
是否可以根据此公式对搜索结果进行排名 - sum(weight1*text 相关性得分,weight2 * 价格)。
I am trying to create a feature that allows search results to be displayed by this formula sum(weight1*text relevance score, weight2 * price). weight1 and weight2 are numeric values that can be changed to influence the search results.
I am sending the following query params to the Solr instance for searching.
q=red
defType=dismax
qf=10^name+2^price
My understanding is that when using dismax, Solr/Lucene looks for the search text in all the fields specified in the qf param.
Currently my search results are similar to those I get when qf does not including a price. I think this is because price is a numeric field and there is not text match.
Is it possible to rank search results based on this formula - sum(weight1*text relevance score, weight2 * price).

你就快到了！ qf 的语法是
qf=field^weight，而不是相反。有关更多详细信息，请参阅本文档。
You were almost there! The syntax of qf is
qf=field^weightand not the other way around.See this document for more details.
