solr ranking

The SOLR server is developed using JAVA5 and is based on the Lucene Full-text search. To build SOLR, first configure the Java environment, install the corresponding JDK, and Tomcat, which is not much to say here. The following is the latest version of solr4.10.3 in jdk1.7 and tomcat1.7 environments. The specific steps are as follows: 1. To the official website http://lucene.apache.org/

Today, I want to use DIH to import CSV files, so the data source is roughly implemented using filedatasource + custom converter. Package COM. besttone. transformer; import Java. util. map; public class csvtransformer {// reference http://wiki.apache.org/solr/DIHCustomTransformerpublic object transformrow (Map Many problems have been found, such as the comma in the field, and so on. This rough converter cannot be implemented, so I continued to find th

Faceted search has become a critical feature for enhancing findability and the user search experience for all types of search applications. In this article, SOLR creator yonik Seeley gives an introduction to Faceted search with SOLR. By yonik SeeleyWhat is Faceted search?Faceted search is the dynamic clustering of items or search results into categories that let users drill into search results (or

We talked about the basic usage and configuration file of SOLR several times before, and then we started our real code journey. 1) start with a simple program: Public static void main (string [] ARGs) throws solrserverexception, ioexception, parserconfigurationexception, saxexception {// Set SOLR. Home. Note that the environment variable SOLR.

1 Overview SOLR is an independent enterprise-class search application server that provides an API interface similar to Web-service. The user can submit a certain format XML file to the Search engine server through HTTP request, generate the index, or can make the lookup request through the HTTP GET operation, and obtain the return result of the XML format. This is mainly explained in this way through HTTP GET requests. First, we have to go through H

As we all know, search engines show search results (Serps) by adding a lot of ranking algorithms to the candidate results, and then sorting the candidate results and finally showing them to the user. We have previously published some ideas on the site weight algorithm, see "original article rankings than reproduced reasons: weight gain" and "Lanzhou SEO again talk about site weight gain" in many rankings algorithm, the major search engines will join t

Mongo-connector integrates MongoDB to Solr for incremental Indexing Configure the MongoDB replica set Deploy a replica set for testing and development Deployment replica set 1. create necessary data folders for each node: 1 mkdir-p/srv/mongodb/rs0-0/srv/mongodb/rs0-1/srv/mongodb/rs0-2 2. Run the following command to start the mongod instance: First node: Mongod -- port 27017 -- dbpath/srv/mongodb/rs0-0 -- replSet rs0 -- smallfiles -- oplogSize 128 --

1Create a collection SSH connects remotely to the CDH node that has SOLR installed. Running the solrctl instancedir--generate/solr/test/gx_sh_tl_tgryxx_2015 command generates the default configuration for the Gx_sh_tl_tgryxx_2015 collection. Enter the/solr/test/gx_sh_tl_tgryxx_2015/conf directory, first edit the Schema.xml configuration field information,

Prerequisites:Installing SOLR Version: 4.8.0 deployment SOLR Path:/data/solr-4.8.01. Upload some configuration information via zookeeper:Upload configuration information to the ZK environment via the ZK command/data/solr-4.8.0/node/scripts/cloud-scripts/zkcli.sh-zkhost solr1-cmd upconfig-confdir/data/

The previous article built the zookeeper clusterWell, today we can build a cluster of SOLR search service, which is different from Redis cluster, it needs ZK management, as an agent layerInstall four Tomcat and modify its port number to not conflict. 8080~8083If it is a formal environment, use 4 Linux nodes respectivelyModify the Server.xml file to modify the port number by a total of 3The above steps are repeated on the tomcat03,tomcat04, but 3 ports

Next year work mainly and search related, in their own learning process to share to let more people benefit is my usual practice, so I will take the study of SOLR here to share with you, if you are also interested in search, but also novice, then you and I start from scratch.Today we are going to talk about the Quick start SOLR, let's play in the window environment, ready, we're about to start.about SOLRSOL

With the wide application of SOLR, SOLR version updates have also accelerated scripts, easynet. SOLR (http://easynet.codeplex.com/) has been in the maintenance of intermittent, today also released the latest version, fully support SOLR 3.5.1. Compared with SOLR client solrsh

Zookeeper can manage the configuration files of SOLR and other software. The configuration file is stored on the disk of the Linux server, but it does not change the location where SOLR reads the SOLR/home configuration file. Currently, the SOLR/home configuration file is located in two places: E: \ apache-Tomcat-7.0.2

Reprinted from: http://www.cnblogs.com/ezhangliang/archive/2012/04/11/2441945.html Scheduler mainly solves two problems: 1. Update indexes on a regular basis. 2. Redo the index regularly. After testing, scheduler has been able to implement completely configuration-based, without the need for development features, without manual intervention to implement the above two features (combined with SOLR data import request handler ). To facilitate later use,

I just deployed SOLR under tomcat, so I ran out of it. I'm so excited. Call ~ In fact, as long as the following conditions are met, the deployment will not fail: 1. Realize that SOLR is a webapp role; 2. Download the war package under the SOLR directory DIST and put it under the Tomcat \ webapps directory. 3. start Tomcat; 4. after Tomcat is started,

I tried the following three open-source Chinese Word divider in SOLR, two of which were not available because the SOLR version was too high. I finally decompiled the jar package and found the reason, the following briefly describes three open source Chinese Word splitters.

Because the search engine features in the portal community to enhance the user experience has focused on the portal community involved in a large number of search engine requirements, there are currently in the implementation of the search engine is a centralized solution to choose:1. Based on Lucene self-encapsulation to achieve in-station search. Workload and scalability are large, not used.2. Call Google, Baidu's API to implement the site search. With third-party search engine binding too dea
