The Elium search engine allows a free text search enriched with metadata and multiple attributes. Elium also allows the indexing of standard files containing text such as word files, powerpoint files and even cells of an excel file.
Like the full text search, filters by means of tags operate according to Boolean logic.
- When the user selects two tags of the same category, an
ORapplies. The user leaves the choice to the presence of one or the other of the two tags in the searched contents. For example, by selecting the tags "Belgium" and "France", both from the same "Country" category, the results display the content tagged "Belgium", tagged "France" and content with the two tags.
- When the user selects two tags from different categories, an
ANDapplies. The user wants the searched content to present both of these tags. For example, by selecting the "Belgium" tag in the "Country" category and the "Food industry" tag in the "Sector" category, the results display contents relating to the food sector in Belgium alone.
Selecting two categories of tags amounts to asking the search engine to only display contents with at least one tag from each selected category. Therefore categories are linked by an
The various selected spaces as filters are always linked by an
OR. The user leaves the choice for searching content of the one or the other space.
The various selected types as filters are always linked by an
OR. The user leaves the choice for searching content of the one or the other type of content.
The various selected contributors as filters are always linked by an
OR. The user leaves the choice of the one or the other contributor.
Activation of the two filters among the additional filters imposes an
AND. For example: I am searching all my archived contents.
