Search
This core feature is based on Elasticsearch (ES). Almost all the information in the portal (including datasets, articles, geographical data) is indexed in ES. This allows lot's of possibilities with the powerful features of this tool.
Here are the features existing on the portal:
- research: thanks to ES great indexation, to go through millions of documents is super fast (millions because we are not only looking inside the metadata, but also inside the data)
- autocompletion: using the score based on some criteria, we provides an autocompletion feature that helps to give a context for some research keywords.
- suggestion: if a research didn't give good or no results (for example because of a typo), a word with more results will be suggested.
Of course there is a plenty of room for improvements for these features (and for new ones). ES is very powerful but also very complex to master. It's in a constant improvement.
Datasets results
As in many search tools the results are displayed in different tabs representing different results categories: All, Data, Services and the News (editorial content).
For each tab these results are paginate with 10 entries per page.
It's possible to sort the results by relevance, date and alphabetically.
