I found that `rare_terms` aggregation can return **false positive**
results (some of the returned results are not real). I traced it
down and find out it's a bug in `CuckooFilter`'s merge methord.
```
if (isSetMode == false && other.isSetMode) {
other.hashes.forEach(this::add);
}
```
should be
```
if (isSetMode == false && other.isSetMode) {
other.hashes.forEach(this::addHash);
}
```
