Include English preflabel when searching Wikidata entities

[rschalkrce]

Users remark that they cannot find all entities in Wikidata because some only have an English preflabel. E.g. https://www.wikidata.org/wiki/Q110519238

Seems to me a good idea to also include English preflabels in the Wikidata search query?

I cannot reproduce this issue?

That is the wrong one: it should also give http://www.wikidata.org/entity/Q110519238 (Agnes van Reede) not only https://www.wikidata.org/wiki/Q76021380 (Agnes van Reede van Drakesteijn)

It also goes for this one: https://www.wikidata.org/wiki/Q11834071 (also no Dutch label)

Proposed solution for the search query:

FILTER(LANG(?rdfs_label) = "nl" || LANG(?rdfs_label) = "en") OPTIONAL { ?item skos:altLabel ?altLabel . FILTER(LANG(?altLabel) = "nl" || LANG(?altLabel) = "en")}

This retrieves both of the provided Q entities that only have an English label

This works indeed despite of the option bd:serviceParam mwapi:language "nl" in the query. Can somebody explain what the effect is of this option?
