Vectorizer

A brief description of the vectorizer feature

Vectorizer​

Configure vectorizer under Index -> Vectorizer

Index​

Use vectorizer configured in prior step for field of type string or inside child field of type nested

Note:

For opensearch a setting in the raw tab need to be set:

{
  "instances": [
    {
      "type": "elastic_aws_7",
      "state": "active"
    }
  ]
}
  1. Configure field in Search -> Searching. Use "dot" notation for nested fields e.g. snippets.text
  2. If custom profile, make sure that the placeholders $qsfql.search, $qsfql.searchVectors, $qsfql.nestedFields are set
  3. Under Variables the vectorizerMinTokens can be set, to activate the vectorizer only at specific query length. Default value is 3
  4. Under Raw tab the vectorizer can be enabled/ disabled per field like follows:
{
  "searchFieldConfigs": [
    {
      "source": "",
      "name": "title",
      "display": true,
      "search": false,
      "suggest": false,
      "suggestPhrase": false,
      "stemmed": false,
      "exact": false,
      "fuzzy": false,
      "facet": false,
      "ranking": 20,
      "vectorize": true
    },
    {
      "source": "",
      "name": "snippets.text",
      "display": true,
      "search": true,
      "suggest": false,
      "suggestPhrase": false,
      "stemmed": false,
      "exact": false,
      "fuzzy": false,
      "facet": false,
      "ranking": 0,
      "lengthPunctuation": "",
      "vectorize": true
    }
  ]
}
