在Solr内部联接中使用IN查询

Question

我在Solr中使用内部联接，以下查询对我来说很好用：

{！join from = _id to = relationships.collection2.key fromIndex = collection2_shard1_replica1 cache = true} _id：{！join from = _id to = relationships.collection3.key fromIndex = collection3_shard1_replica1 cache = true} name：“cloudProducts”

现在，我正在尝试使用IN查询名称条件，例如名称:(“cloudProducts”或“mobileStation”或“standAlone”），因此我将查询设为：

{！from from = _id to = relations.covered.targets.key fromIndex = app.coveredassets_shard1_replica1 cache = true} _id：{！join from = _id to = relationships.product.targets.key fromIndex = app.products_shard1_replica1 cache = true} str_extensions.tenant.lineOfBusiness.value.name :(“cloudProducts”或“mobileStation”或“standAlone”）

但是它给出了解析异常。我试过操纵语法但没有成功。是否可以在Solr内连接中使用IN查询？谁能帮我这个？

Answer 1

我能够通过将内部查询传递给＆＃39; v＆＃39;来解决这个问题。内连接中的关键字。

{！from from = _id to = relations.covered.targets.key fromIndex = app.coveredassets_shard1_replica1 cache = true} _id：{！join from = _id to = relationships.product.targets.key fromIndex = app.products_shard1_replica1 cache = true v = str_extensions.tenant.lineOfBusiness.value.name :(＆＃34; cloudProducts＆＃34; OR＆＃34; mobileStation＆＃34; OR＆＃34; standAlone＆＃34;）}

OR

你可以使用v = $ innerQuery并在Solr params中传递内部查询的值。

{！from from = _id to = relations.covered.targets.key fromIndex = app.coveredassets_shard1_replica1 cache = true} _id：{！join from = _id to = relationships.product.targets.key fromIndex = app.products_shard1_replica1 cache = true v = $ innerQuery}

PARAMS： distrib = false＆amp; innerJoinQuery1 = str_extensions.tenant.lineOfBusiness.value.name :(＆＃34; cloudProducts＆＃34; OR＆＃34; mobileStation＆＃34; OR＆＃34; standAlone＆＃34;）
