Specifically "Query Filters"
and "A single query containing != or contains() operators is limited
to 30 sub-queries."
|| is mapped to 'contains()'

I'm interested in knowing how well multiple OR (||) statements would
operate in a single query. For example, I want to find all friends

"(username == 'turtle' ||
username == 'frog' |
