queries for a set of values
...ke:
std::vector<Xapian::Query> subq;
for (size_t i = 0; i < nelem; i++) {
std::string v = sortable_serialise(int_vals[i]));
subq.insert(Query(OP_VALUE_RANGE, column, v, v));
}
Query(OP_OR, subq.begin(), subq.end());
It seems what I'm really looking for is an OP_VALUE_OR or OP_VALUE_IN;
but only OP_VALUE_{GE,LE,RANGE} exists.
[1] Even if I switched to terms, I would still keep the numeric
values since I also rely on Enquire.set_collapse_key on this
column.

You can build it up the same way with:
filter |= Query(OP_VALUE_RANGE, column, v, v);
> It seems what I'm really looking for is an OP_VALUE_OR or OP_VALUE_IN;

Just use OP_VALUE_RANGE with equal bounds.
Another approach is to use a custom PostingSource which can fetch the
value for that slot for each document being considered and check if it's
one of the values you want.
