问题 Ok here's one at which I've been scratching my head at without great success so far; Sorry in advance for the very long question...

configuring nutch regex-normalize.xml

由 丶灬走出姿态 提交于 2019-12-25 15:22:08
问题 I am using the Java-based Nutch web-search software. In order to prevent duplicate (url) results from being returned in my search query results, I am trying to remove (a.k.a. normalize) the expressions of 'jsessionid' from the urls being indexed when running the Nutch crawler to index my intranet. However my modifications to $NUTCH_HOME/conf/regex-normalize.xml (prior to running my crawl) do not seem to be having any effect. How can I ensure that my regex-normalize.xml configuration is being

Solr Customization using Java for modified output?

由 蹲街弑〆低调 提交于 2019-12-25 10:30:28
问题 I am developing an application uaing Solr. Everything is going fine and I am looking ahead to integrate Solr with CodeIgniter or some other framework for frontend. But there is a problem. I am performing some calculations on output rows thrown by Solr and showing them to users. It is really not feasible to do in PHP ( as it takes really long time). I have an existing code written in Java and hence, I find no reason in porting this application to PHP. How can I do that? Is there anyway I can

Obtain metadata associated with matched content in Solr/Lucene

由 空扰寡人 提交于 2019-12-25 09:33:20
问题 I've a large set of text documents which I will index with Solr, in a format where each line of text has associated metadata. For example: #metadata1 A line of text. #metadata2 Another long, broken line of #metadata3 text that should be searchable. I'd like to index this such that the content is searchable, including phrase matches spanning multiple lines, but not the metadata. However, I can't discard the metadata: I would like to have any matches still have the associated metadata. E.g. A

Docker 简单部署 ElasticSearch

由 你。 提交于 2019-12-25 08:03:06
一、ElasticSearch是什么? Elasticsearch也使用Java开发并使用Lucene作为其核心来实现所有索引和搜索的功能，但是它的目的是通过简单的RESTful API来隐藏Lucene的复杂性，从而让全文搜索变得简单。 不过，Elasticsearch不仅仅是Lucene和全文搜索，我们还能这样去描述它： 分布式的实时文件存储，每个字段都被索引并可被搜索 分布式的实时分析搜索引擎 可以扩展到上百台服务器，处理PB级结构化或非结构化数据 拉取镜像 docker pull elasticsearch:6.7.2 docker pull mobz/elasticsearch-head:5 docker pull kibana:6.7.2 运行容器 ElasticSearch 的默认端口是9200，我们把宿主环境9200端口映射到 Docker 容器中的9200端口，就可以访问到 Docker 容器中的 ElasticSearch 服务了，同时我们把这个容器命名为 es 。 docker run -d --restart=always --name es -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" elasticsearch:6.7.2 配置跨域 进入容器 由于要进行配置

Can we make Lucene IndexWriter serializable for ExecutionContext of Spring Batch?

由 雨燕双飞 提交于 2019-12-25 07:59:09
问题 This question is related to my another SO question. To keep IndexWriter open for the duration of a partitioned step, I thought to add IndexWriter in ExecutionContext of partitioner and then close in a StepExecutionListenerSupport 's afterStep(StepExecution stepExecution) method. Challenge that I am facing in this approach is that ExecutionContext needs Objects to be serializable. In light of these two questions, Q1, Q2 -- it doesn't seem feasible because I can't add a no - arg constructor in
