How to compare two columns using Solr?

问题 Compare two columns in solr if two fields are equal display true or else false. CASE WHEN o_is_follow = o_follow_id THEN 'TRUE' ELSE 'FALSE'. 回答1: As per as I know comparing one field to another within a document is not supported in either Solr . I think it can be achieved by one option of creating another field while indexing only. You can have another field (boolean) . Make this field as boolean type and can be used while searching. Create a o_is_follow_present field and set it to true for

Solrj formats my dates from UTC to CEST

由 我们两清 提交于 2019-12-11 11:28:22
问题 I just discovered a problem with a date field in my application. I have a date field that is indexed in Solr in UTC format. For instance, "parution_date": "2014-09-29T22:00:00Z", . When I make request to Solr using a pivot, and I want to get this value, Solr converts my date to CET (I'm in Europe). Here the date I received for the same document: Tue Sep 30 00:00:00 CEST 2014 . As you see here, instead of keeping the date to its original format which is UTC, it converts the date CEST. I want

全文检索可视化动态管理（二）--solr二次开发和solrj扩展

由 我的未来我决定 提交于 2019-12-11 10:11:19
【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 要完成solr的索引动态配置，需要solr提供动态新建、修改配置等的接口。solr虽提供core的添加删除，但不提供schema.xml修改新建接口，并且如果添加一个新core，也要将另一个core的conf配置文件复制一份到新的core文件夹下，然后管理页载入新的core。因此需要二次开发。 查看solr的web.xml，可以发现请求链接都进入org.apache.solr.servlet.SolrDispatchFilter。查看SolrDispatchFilter源码，可以在doFilter方式里看到，如果是adminPath的链接,则SolrRequestHandler的实现是cores.getMultiCoreHandler()。 进入getMultiCoreHandler()方法，可以得知是org.apache.solr.handler.admin.CoreAdminHandler。此类则是solr管理界面的Core Admin的接口处理类。因此，可以继承CoreAdminHandler，重载handleRequestBody方法来给solr增加所需的处理接口。 进一步查看源码，可以发现solr.xml里可以用adminHandler标签替换CoreAdminHandler。solr.xml： <

Solrj Block Join Bean support

由 本秂侑毒 提交于 2019-12-11 05:48:14
问题 I would like to use a Solrj Bean to save/query nested documents from Solr. Is this possible? I see that since version 4.5 it is possible to use addChildDocument(SolrInputDocument child) but looking at the source code for org.apache.solr.client.solrj.beans.DocumentObjectBinder I see that nested documents are not taken into consideration. A new annotation additional to the @Field annotation would also be required I guess. Does anyone have any experience with this? 回答1: If you want to insert
