Detailed Description

Handles the search keyword 'haswbstatement:'.

Allows the user to search for pages/items that have wikibase statements associated with them.

If a file page has the statement 'wikidata:P180=wikidata:Q527' (meaning 'depicts sky') associated with it then it can be found by including 'haswbstatement:wikidata:P180=wikidata:Q527' in the search query.

If a file page has the statement 'wikidata:P2014=79802' (meaning 'MoMA artwork id 79802') associated with it then it can be found by including 'haswbstatement:wikidata:P2014=79802' in the search query.

Statements can be combined using logical OR by separating them with a | character in a single haswbstatement query e.g. 'haswbstatement:P999=Q888|P999=Q777'

Statements can be combined using logical AND by using two separate haswbstatement queries e.g. 'haswbstatement:P999=Q888 haswbstatement:P999=Q777'

Note that NOT ALL STATEMENTS ARE INDEXED. Searching for a statement about a property that has not been indexed will give an empty result set.
