Exact match features

The exact match features help to ensure more intuitive ordering of search results.

You can enable and disable the exact match features in the boost settings. Both features are enabled, by default.

Exact Match Boost

This feature ensures that exact search text matches in the Name attribute of a resource always appear first in the search results, regardless of boost factors.

Prerequisites

  • The following assets exist in your Collibra environment:
    • A Schema asset with the name "Payment"
    • A Business Term asset with the name "Payment Type".
    • A Data Attribute asset with the name "Payment Type".
    • A Policy asset with the name "Payments".
    • Other assets, as shown in the following image.
  • Edit asset type boost factors, in Collibra Console, as follows:
    • Business Term: 3
    • Data Attribute: 2
    • Policy: 1.5

Search text

Enter search text "payment".

Results

The resources that exactly match the search text in the Name attribute of the resource appear first. In this example, there is only one exact match, the Schema asset with the name "Payment".

After the exact matches, the search results are sorted in order of descending relevance.

Partial Exact Match

This feature is only relevant for multi-word search text. In this case, the search engine considers the exact match percentage with the asset name, when ordering the results.

Example You enter search text "scheduled maintenance". Two example assets are ordered as follows:
  1. An asset named "daily scheduled maintenance", as two of the three words (66%) match exactly.
  2. An asset named "daily scheduled maintenance revised", as two of the four words (50%) match exactly.
