01. Solr7.3.1 deployment and configuration of jetty under win10 platform

What is? Solr

Solr yes Apache Next top open source project , use Java Development , It is based on Lucene Full text search server for .Solr Provides a ratio Lucene Richer query language , At the same time, configurable 、 Scalable , And index 、 Search performance optimized

Solr Can run independently , Running on the Jetty、Tomcat Such as these Servlet In the container ,Solr The implementation of index is very simple , use POST Method direction Solr Server sends a description Field And its contents XML file ,Solr according to xml Document add 、 Delete 、 Update index .Solr Search only needs to be sent HTTP GET request , Then on Solr return Xml、json Analysis of query results in equal format , Organize page layout .Solr Build not available UI The function of ,Solr Provides a management interface , Query through the management interface Solr Configuration and operation of .

solr Is based on lucene Develop enterprise search server , It's actually encapsulation lucene.

Solr Is an independent enterprise search application server , It is similar to Web-service Of API Interface . The user can go through http request , Submit a file in a certain format to the search engine server , Build index ; You can also make a search request , And get the return result

Solr similar webservice, Call interface , Realize increase , modify , Delete , Query index library .

Solr And Lucene The difference between

Lucene Is an open source full-text search engine toolkit , It is not a complete full-text search engine ,Lucene Provides a complete query engine and index engine , The goal is to provide software developers with an easy-to-use toolkit , In order to facilitate the realization of full-text retrieval in the target system , Or with Lucene Build a full-text search engine based on .

Solr The goal is to build an enterprise level search engine system , It's a search engine service , Can run independently , adopt Solr Can be very fast to build enterprise search engine , adopt Solr It can also efficiently complete the search function in the station .

Solr similar webservice, Provide the interface , Call interface , Send some characteristic statements , Realize increase , Delete , modify , Inquire about .

1、solr Download and install

Download address ： http://www.apache.org/dyn/closer.lua/lucene/solr/7.3.1

2 install solr

After downloading , take solr-7.3.1.zip Send it under your specific drive letter . But be careful that this directory had better not have spaces , Chinese or other special characters .

3、 start-up solr

decompression solr-7.3.1.zip after , Enter its bin Catalog ： In the blanks shift+ Right mouse button , Get into Powershell window ：

Then input cmd.exe

solr 7.3 Bring their own jetty, Can run independently , No need to use Tomcat start-up .

Input solr.cmd start Then knock back , You can start it solr 了 . The default port is ：8983

Type in the browser localhost:8983/solr, You can see that solr It's already started

4、 Create the core core

So-called core By analogy mysql Database to understand , like mysql One by one database , A warehouse for storing specific data tables .

Remember that you cannot directly use the add core To create core

In the window just opened , Input solr.cmd create -c test_Core

At this point, enter server\solr, You can see that a test_Core Catalog

Enter this directory

After creation , Refresh the page , At the same time, in the drop-down box in the figure, you can see the Core 了 . If you can't see it , stay dos Window type solr restart -p 8983 restart solr that will do

Click on myCore You can see the following information ： This information includes the word breaker , And data import , Data query and other functions

5、 start-up solr And the creation of core When it's done , This step configures the Chinese word splitter ：

Add Chinese word segmentation plug-in ：solr 7.3.1 Chinese word segmentation plug-in comes with , take solr-7.3.1\contrib\analysis-extras\lucene-libs\lucene-analyzers-smartcn-7.3.1.jar Copied to the solr-7.3.1\server\solr-webapp\webapp\WEB-INF\lib Directory

Paste to the target path ：

Configure Chinese word segmentation , modify solr-7.3.1\server\solr\test_Core**【 This test_Core It was just created core name 】**\conf\managed-schema file , Add Chinese word segmentation

file location ：

After opening this file , Search for Italian, stay Italian Add our Chinese configuration （ Copy and paste ）：

 <!-- Italian --> <!--  Configure Chinese word breaker --> <fieldType name="text_cn" class="solr.TextField" positionIncrementGap="100"> <analyzer type="index"> <tokenizer class="org.apache.lucene.analysis.cn.smart.HMMChineseTokenizerFactory"/> </analyzer> <analyzer type="query"> <tokenizer class="org.apache.lucene.analysis.cn.smart.HMMChineseTokenizerFactory"/> </analyzer> </fieldType> 

Copy

Configuration complete ：

Use solr restart -p 8983 restart solr service

Refresh to open the management page

Test Chinese word breaker ：

6 、 Configure Chinese word breaker IK-Analyzer-Solr7

Adapt to the latest version solr7, And add the function of dynamically loading dictionary table ;

No restart is required solr Load the new dictionary in the case of service .

To download solr7 Version of ik Word segmentation is , Download address ：http://search.maven.org/#search%7Cga%7C1%7Ccom.github.magese

Word segmentation is GitHub Source code address ：https://github.com/magese/ik-analyzer-solr7

GitHub There is a way to use the word separator

Will download okay jar Put in bags solr-7.3.1/server/solr-webapp/webapp/WEB-INF/lib Directory

And then to solr-7.3.1/server/solr/test_Core/conf Open... In the directory managed-schema file , Add the following configuration

<!-- ik Word segmentation is  --> <fieldType name="text_ik" class="solr.TextField"> <analyzer type="index"> <tokenizer class="org.wltea.analyzer.lucene.IKTokenizerFactory" useSmart="false" conf="ik.conf"/> <filter class="solr.LowerCaseFilterFactory"/> </analyzer> <analyzer type="query"> <tokenizer class="org.wltea.analyzer.lucene.IKTokenizerFactory" useSmart="true" conf="ik.conf"/> <filter class="solr.LowerCaseFilterFactory"/> </analyzer> </fieldType> 

Copy

take gitHub Download the original code resources In the catalog 5 Configuration files are put into solr Service jetty or tomcat Of webapp/WEB-INF/classes/ Under the table of contents （ If WEB-INF Under no classes Catalog , Then create it manually ）;

①IKAnalyzer.cfg.xml
②ext.dic
③stopword.dic
④ik.conf
⑤dynamicdic.txt

Copy

ext.dic To expand the dictionary ;

stopword.dic Dictionary for stop words ;

IKAnalyzer.cfg.xml For profile .

Each word is on a separate line

Restart again after configuration solr service

Participle test

For me, , yes , No more （ Because in stopword.dic Stop words are configured in the dictionary ）.

thus .Solr Configuration complete .
