Help/SemanticSearchPlugin

Search for relations/attributes and its values.

page - relation::object. e.g list all cities: is_a::city => relation=is_a&s=city

We search for both a relation and if the search is valid for attributes also, and OR combine the result.

An attribute has just a value, which is a number, and which is for sure no pagename, and its value goes through some units unification. (not yet)

We can also do numerical comparison and unit lifting with attributes:

  • population > 1000000
  • population > 1 million

Limitation:

  • The backends can already do simple AND/OR combination of multiple relations and attributes to search for. Just the UI not. TODO: implement the AND/OR buttons. population < 1 million AND area > 50 km2
  • Due to attribute internals a relation search with matching attribute names will also find those attribute names, but not the values. You must explicitly search for attributes then.

The Advanced query can do a freeform query expression with multiple comparison and nesting.
