Introduction to Lucene 3.6.2 (Solr3.6.2) Overview and integrated Tomcat

/**
* "Lucene3.6.2 Introductory series" 13th section _solr3.6.2 Introduction and integrated tomcat
* @see SOLR is a high-performance, JAVA5 developed, open source Enterprise Full-text search engine based on HTTP and Lucene implementation
* @see can be roughly understood as: Lucene focuses on search-bottom implementation and algorithmic optimization, and SOLR focuses on high-level, easy-to-use and managed search servers for Enterprise Services
* @see a little bit more rough to understand: the relationship between Lucene and SOLR is similar to the relationship between Ajax and Jquery,servlet and Struts2,jax-ws and Cxf,nio and Mina
* @see SOLRJ is the interface to SOLR's Java-based access SOLR server, which provides the CRUD (add-check) and optimized interface for indexing the SOLR server

* @see 1) New Folder D:\Develop\apache-solr-3.6.2\ folder on local hard disk
* @see 2) and create a new D:\Develop\apache-solr-3.6.2\home\ folder
* @see 3) Copy the contents of the downloaded apache-solr-3.6.2.zip\example\solr\ to the new home folder in the previous step
* @see 4) Empty the contents of the D:\Develop\apache-solr-3.6.2\home\data\ folder

* @see 6) Copy the Solr.war from the downloaded apache-solr-3.6.2.zip\example\webapps\ to the new server folder in the previous step
* @see then unzip the files in the Solr.war in the current directory, the server folder

* @see <datadir>${solr.data.dir:d:\develop\apache-solr-3.6.2\home\data} </dataDir>
* @see In fact this step can also put the data directory into the environment variables, and then use ${environmentvariable} on the reference to the
* @see 8) Edit the 144th line of D:\Develop\apache-tomcat-6.0.36\conf\server.xml (that is, the <Hots> tab) for the following value
* @see <context path= "/SOLR" docbase= "D:\Develop\apache-solr-3.6.2 \server\solr" reloadable= "false"/>
* @see 9) Set the corresponding environment variable for <Context/>, indicating the address of SOLR's home directory, after modification.

* @see [Precautions]
* @see for Apache-solr-3.5.0.zip, the following exception may be reported in the end when Tomcat is started
* @see Serious: Org.apache.solr.common.SolrException:Error loading class ' SOLR. Velocityresponsewriter '
* @see caused BY:JAVA.LANG.CLASSNOTFOUNDEXCEPTION:SOLR. Velocityresponsewriter
* @see the 1554th line of the D:\Develop\apache-solr-3.6.2\home\conf\solrconfig.xml file should be modified (line 1573th for solr-3.6.2)
* @see <queryresponsewriter name= "Velocity" class= "SOLR". Velocityresponsewriter "enable=" ${solr.velocity.enable:false} "/>

* @see 1) A large number of domains are defined in this file, and each domain specifies the word breaker defined in each domain in Fieldtype,fieldtype.
* @see 2) We can define the domain directly with SOLR, or we can customize the domain, and the first domain in the large number of fields provided by SOLR is the ID field, and its required is true, that is, the required
* @see We can use its ID field directly, or we can customize the ID field, but only one domain required= "true"
* @see 3) and in the program to use the domain name, must be specified in the Schema.xml, otherwise it will report the following exception
