Setting the Stage
Before you leap into action, make sure the Analysis-ALIWS plugin is installed. It’s not part of the default setup and requires your attention to get started. Check out this guide for the installation walkthrough.
Configuration Journey
Step 1: Index Creation
Begin by accessing the Kibana console of your Elasticsearch cluster. Head over to Dev Tools and deploy the following command to create an index:
For versions before V7.0:
PUT /index
{
"mappings": {
"fulltext": {
"properties": {
"content": {
"type": "text",
"analyzer": "aliws"
}
}
}
}
}
For V7.0 and onwards:
PUT /index
{
"mappings": {
"properties": {
"content": {
"type": "text",
"analyzer": "aliws"
}
}
}
}
A successful execution will be confirmed with an acknowledgment.
Step 2: Document Management
Adding a Document:
POST /index/fulltext/1
{
"content": "I like going to school."
}
Searching for a Document:
GET /index/fulltext/_search
{
"query": {
"match": {
"content": "school"
}
}
}
Dictionary Upload
Head to Configuration and Management > Plug-ins in the Elasticsearch console. Locate the Analysis-ALIWS plugin and select Dictionary Configuration to upload your aliws_ext_dict.txt file.
Experimentation and Personalization
Testing the aliws analyzer:
GET _analyze
{
"text": "I like going to school.",
"analyzer": "aliws"
}
Customizing the Tokenizer:
Adjust your tokenizer by setting up filters such as stemmer, lowercase, porter_stem, and stop to suit your specific needs. Here’s how:
PUT my-index-000001
{
"settings": {
"analysis": {
"filter": {
"my_stop": {
"type": "stop",
"stopwords": [" ", ",", ".", "　", "a", "of"]
}
},
"analyzer": {
"my_custom_analyzer": {
"type": "custom",
"tokenizer": "aliws_tokenizer",
"filter": ["lowercase", "porter_stem", "my_stop"]
}
}
}
}
}
