The search engine use Apache Solr and the user interface is rendered through a stack of JavaScript behaviors on top of the Django Framework

The index includes all data types of the Database. Then, it’s now possible to search in a unified manner across Indicators but also Resources and Project data package (+ Dataset if you are connected to the Data Upload). Note that Indicators are setup with higher ranking than the other content types. 

Facets exposes the dimensions and characteristics of the Database and each facets items include a filter which allow the user to drill down through and narrow his research.

The keywords search is made across multiple fields of the database which are indexed "offline" (e.g.: title, abstract, keywords, territorial information, etc, ...) during an asynchronous task. Note that a “boosting” parameter is made on title so matching and that field will be ranked higher. An Autocomplete behavior is applied to this input which suggest words combination originating from the Database.

Finally, the facets filters or the keywords search is made through asynchronous requests without loading the whole page. This improves the user interface response performance but also provides an improved user experience since the stats of the page is kept across the different requests (e.g.: opened facet a kept open).

Main types

Indicator Key data 

Indicators that are considered by the projects as their main results. As outputs of different types of data processing, they may have multiple parent (background) indicators. All key indicators use a standard nomenclature.” => full metadata.
