How to Enable Elasticsearch in VIDIZMO

Portal Managers can enable or disable Elasticsearch functionality for different areas of the portal. When Elasticsearch is enabled for media search, search weight settings become available to control how different content fields are prioritized in search results.

For information about Elasticsearch capabilities in VIDIZMO, see Understanding VIDIZMO's Elasticsearch.

Prerequisites​

  • Ensure you belong to a group with Portal Settings management permissions.

Enable Elasticsearch​

  1. Select the navigation menu.
  2. Expand Admin.
  3. Select Settings.
  4. Expand Library.
  5. Select Search Providers.
  6. Enable the Elasticsearch options based on your requirements:
    • Enable Elastic Search for Audit Log Indexes and searches audit log entries.
    • Enable Elastic Search for Media Search Enables Elasticsearch for media content search. When enabled, search weight configuration fields appear (see Configure Search Weights).
    • Enable Elastic Search for Consumption Reports Enables Elasticsearch for consumption reporting and analytics.
  7. Select Update.

Note: Each option functions independently. Enable any combination based on your organization's needs.

Configure Search Weights​

When Enable Elastic Search for Media Search is enabled, search weight fields appear below the checkbox. These weights control how much priority each content field receives when ranking search results. A higher weight increases the influence of that field on the search ranking.

All weight values accept a number between 0 and 100 with a step increment of 0.1.

Keyword Search Weights​

Keyword search weights control how traditional text-based search results are ranked. Increase a weight to prioritize matches in that field; decrease it to reduce its influence.

  • Title Search Weight (Default: 1) Controls the priority of matches found in content titles.
  • Description Search Weight (Default: 1) Controls the priority of matches found in content descriptions.
  • Tags Search Weight (Default: 1) Controls the priority of matches found in content tags.
  • Custom Attributes Search Weight (Default: 1) Controls the priority of matches found in custom attribute values.
  • Timed Data Search Weight (Default: 1) Controls the priority of matches found in timed data such as transcripts, captions, and chapters.

Semantic Search Weights​

Semantic search weights control how vector-based similarity results are ranked. Semantic search finds conceptually related content even when exact keywords do not match. Increase a weight to prioritize semantic similarity for that field.

  • Semantic Search Weight (Title & Description) (Default: 1) Controls the priority of semantic similarity matches based on title and description embeddings.
  • Semantic Search Weight (Timed Data) (Default: 10) Controls the priority of semantic similarity matches based on timed data (transcript) embeddings.

Note: The default value for Semantic Search Weight (Timed Data) is 10, which gives significantly more weight to transcript semantic similarity compared to other fields. Adjust this value based on whether your content relies heavily on spoken or transcribed text.

How Search Weights Work​

VIDIZMO uses a hybrid search approach that combines keyword-based matching and semantic vector search. The search weights determine how results from each approach are scored and ranked:

  • Keyword search weights (Title, Description, Tags, Custom Attributes, Timed Data) apply boost values to traditional text matching. When a search term matches content in a specific field, the weight for that field multiplies the relevance score.

  • Semantic search weights (Title & Description, Timed Data) apply boost values to vector similarity search. These weights control how much influence semantic similarity has in the combined search ranking.

Setting a weight to 0 effectively excludes that field from influencing search rankings. Setting a higher weight increases its influence relative to other fields.

After adjusting the search weight values, select Update to apply the changes. The updated weights take effect on subsequent search queries across the portal.
