    "analysis": {
      "analyzer": {
        "synonym_analyzer": {
          "tokenizer": "standard",
          "filter": ["lowercase", "[1]"]
        }

💡 Hint

Common Mistakes

Using a filter name that does not exist or is unrelated to synonyms.

The analyzer must include the synonym filter named synonym_filter to apply synonyms.

Fix the error in the synonym filter definition by completing the missing setting.

Elasticsearch

{
  "settings": {
    "analysis": {
      "filter": {
        "my_synonym_filter": {
          "type": "synonym",
          "synonyms_path": "[1]"
        }
      }
    }
  }

💡 Hint

Common Mistakes

Using absolute paths that Elasticsearch cannot access.

The synonyms_path should be a relative path or filename accessible by Elasticsearch, commonly just the filename like synonyms.txt.

4fill in blank

hard

Fill both blanks to create a synonym filter that expands synonyms and ignore case.

Elasticsearch

{
  "settings": {
    "analysis": {
      "filter": {
        "expanded_synonym": {
          "type": "[1]",
          "expand": [2],
          "synonyms": ["car, automobile"]
        }
      }
    }
  }
}

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using 'stop' as filter type or setting expand to false when expansion is needed.

The filter type is synonym and setting expand to true makes synonyms expand.

5fill in blank

hard

Fill all three blanks to define an analyzer that uses the synonym filter, lowercase filter, and standard tokenizer.

Elasticsearch

{
  "settings": {
    "analysis": {
      "analyzer": {
        "custom_synonym_analyzer": {
          "tokenizer": "[1]",
          "filter": ["[2]", "[3]"]
        }
      }
    }
  }
}

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using stop filter instead of synonym filter or wrong tokenizer.

The analyzer uses the standard tokenizer, then applies lowercase and synonym_filter filters.
