Elasticsearch version 7.3

Install the synonym plugin

The corresponding version of the plug-in needs to be the same as the version of elasticsearch

Plug-in download address

Https://github.com/bells/elasticsearch-analysis-dynamic-synonym

The installation steps are as follows:

Create a new analysis-dynamic-synonym folder under the elasticsearch-7.3.0/plugins directory

If it is the latest version of master, you need to use maven to compile the jar and put it in the folder you just built. If it is another version that has already been compiled, you can copy it directly. In this case, you need the compiled version.

Add plugin-descriptor.properties and plugin-security.policy at the same time, see below for details

Restart the cluster

The remote thesaurus is also based on Last-Modified and ETag in http header to determine whether it needs to be updated. For more information, please refer to my other blog article, which is the same elasticsearch Chinese word segmentation plug-in IK-Analyze.

After compilation, you only get a jar package. In fact, the elasticsearch installation plug-in also needs the configuration file plugin-descriptor.properties. If there is no such file, an error will be reported. The contents of the file are as follows.

Description=Analysis-plugin for synonymversion=5.1.1name=analysis-dynamic-synonymclassname=com.bellszhu.elasticsearch.plugin.DynamicSynonymPluginjava.version=1.8elasticsearch.version=7.3.0

You also need to put in the configuration file plugin-security.policy

Grant {/ / needed because of the hot reload functionality permission java.net.SocketPermission "*", "connect,resolve";}

If elasticsearch reports the wrong message

Failed to get synonyms: http://10.0.11.1:10002/elasticsearch/synonymDictaccess denied ("java.net.SocketPermission"10.0.11.1 denied 10002"connect,resolve")

The reason is the missing plugin-security.policy file.

Commons httpclient these jar can be downloaded from a lower version of the plug-in.

All files of the plug-in are as follows:

Test synonym plug-in

Create an index that specifies a remote thesaurus

PUT / full_text_test123 {"settings": {"index": {"analysis": {"analyzer": {"ik_syno_smart": {"tokenizer": "ik_max_word", "type": "custom" "filter": ["remote_synonym"]}, "filter": {"remote_synonym": {"type": "dynamic_synonym", "synonyms_path": "http://10.0.11.1:10002/elasticsearch/synonymDict"," "interval": 30}}, "mappings": {"properties": {"content": {"type": "text", "analyzer": "ik_syno_smart", "search_analyzer": "ik_smart"}

Add synonyms

Executive parser

POST / full_text_test123/_analyze {"text": ["tomato"], "analyzer": "ik_syno_smart"}

Result

{"tokens": [{"token": "tomato", "start_offset": 0, "end_offset": 3, "type": "CN_WORD", "position": 0}, {"token": "tomato", "start_offset": 0, "end_offset": 3 "type": "SYNONYM", "position": 0}]} so far The study on "how to install elasticsearch Chinese word segmentation plug-in Synonym-Analysis" is over.
