[Dashboard] Global Search (Maps & Datasets)

Implement global Map and Dataset search.

We can use the existing /viz endpoint with the following parameters so that it returns both maps and datasets: &types=table,derived&q=<search_term>.

• Results page shows maps and datasets.
• Search by :tag.
• Search suggests results as the user types.
• Clicking on a tag (Map / Dataset) searches for Maps and Datasets with that tag.
• Paginate results.
• Order results by relevance.

@gonzaloriestra I added another task in the description: “Order results by relevance.”. Let’s close this once that work is merged. Thank you!

Maybe we can start with one of the predefined ranking functions by PostgreSQL, which will give better results than random or alphabetical IMO. According to the docs:

It takes into account lexical, proximity, and structural information; that is, they consider how often the query terms appear in the document, how close together the terms are in the document, and how important is the part of the document where they occur.

And then, if we want, we can try to build our own ranking function by adding more information: dataset likes, better score for title vs description, updated_at (we are not counting visits AFAIK)…
