Label:SolrDocumentObjectiveBecause SOLRwas used in the project, it took more than a week to study SOLR, and I did not say any of the questions, especially in the two days when I was studying timing incremental indexing, I didn't know how many XXX in the Pentium, okay, nonsense not much to say, the following I have to share the results of research, and also for SOLR is what, everybody still self-degree niang

Chapter 1 Meet HadoopData is large, the transfer speed is not improved much. it's a long time to read all data from one single disk-writing is even more slow. the obvious way to reduce the time is read from multiple disk once.The first problem to solve is hardware failure. The second problem is that most analysis task need to be able to combine the data in different hardware. Chapter 3 The Hadoop Distributed FilesystemFilesystem that manage storage h

The Apache SOLR project is an open-source enterprise search Server Based on Apache Lucene, and version 1.3 has been released recently. Infoq interviewed the SOLR creator yonik Seeley and learned more about the new version and the functions provided by SOLR to end users. Seeley first describes the target user: "search box, faceted browsing (navigation), or anyon

Solr 5.3 import SQL Server Data I have explained the solr configuration in the previous article. As you can see, I will not talk about it here. The following configuration is done on the premise that solr has been successfully integrated into tomcat. Go to the topic, 1. Modify solr-data-config. Xml file, the content is

At present, more suitable for Java search engine construction will generally choose SOLR, the underlying operation will use SOLRJ interaction, in fact, SOLR is based on Lucene. The implementation process found that many of the Web documents on Java Integration SOLR are based on the solr5+ version, and for the solr7+ version of the document is very small, and many

SOLR Incremental Index configuration 1. Before you perform an incremental index, you must first understand a few of the necessary attributes, as well as database-building-list matters, and dataimporter.properties data-config.xml Data Database Configuration Considerations 1. If only to add, and modify the business, then only one additional Timpstamp field in the database can be, the default value is the current system time, Current_timestamp (the

Download SOLR, tomcat, and ant from the Apache website. After SOLR is compiled with ant, * SOLR *. War is generated in the DIST directory of SOLR. You can copy the war to Tomcat webapp. You can also specify the location of the war and SOLR/home by using JNDI. Because

SORL is a search technology. SOLR runs a Web project that queries the index library for SOLR connections by accessing the Web project. Common Search Technologies 1. Using Lucene alone to achieve: the low-level: the need to develop a large workload, mainly in: index maintenance, index performance optimization, search performance optimization, etc., so it is not recommended. 2. Using Google or Baidu interfac

Release date:Updated on: Affected Systems:Apache Group solrDescription:--------------------------------------------------------------------------------Bugtraq id: 64427CVE (CAN) ID: CVE-2012-6612 Solr is a Lucene-based search server available for enterprises. UpdateRequestHandler for XSLT or XPathEntityProcessor in Apache Solr 4.1 or earlier versions allows remote attackers to execute malicious attacks by u

in the previous article we introduced the full-volume update SOLR index, but when the volume of data is large, frequent updating of the index will consume system performance, if the update frequency is low, it will affect the short-term data accuracy, so the interval of the update time is difficult to define. Incremental indexing solves this problem, we can only update those changes in a short period of time, so as to avoid a large number of data upda

Ok, I wrote the SOLR content again, yesterday made a change and increment of the incremental index, today say about the deletion of the incremental index and the scheduled update of the incremental index, nonsense said, the following into the text.One, the deletion of incremental indexAs I said yesterday, the incremental index is actually the index of the data that the database has changed since the last time the index was done (incremental or full),
