Adds an or condition to the query.
The or() function adds an inclusive or condition to an EventsQueryBuilder. A query
with an or returns all the items that match the query as defined up to
the or function, the items that match the query passed to the or
function, and the items that match both.
The or() function is designed to work with 2 or more queries.
If you use it on its own, it will return all the items in a collection.
Contains functionality for refining a Wix events query.
