[Website] [Blueprints Page] Search filter shows unrelated blueprints

### Describe the issue

On the Website Blueprints page, the search filter does not work correctly. When typing the exact name of a blueprint, it still shows other blueprints. It looks like the search is matching individual words instead of the full search text.

### Reproducibility and Visuals

### Expected Behaviour

Searching with the exact blueprint name should show only the matching blueprint.

Start by reproducing the search behavior on the Website Blueprints page using an exact blueprint name, then trace the page's search-filter entry point. Done means an exact blueprint-name search shows only the matching blueprint and no unrelated blueprints.
