<!-- Answer -->
To resolve the issue of the unsupported predicate 'containing(Template)'
when using the Cypher API to query your graph, you can use an alternative
approach by converting the predicate to a supported one. Specifically, you can
use the `within` or `without` predicates.
Here is an example of how you can handle the `containing` predicate by
converting it to a supported predicate:
```java
switch ((Contains) bp) {
case within:
return Condition.in(pkey.id(), valueList);
case without:
return Condition.nin(pkey.id(), valueList);
default:
throw newUnsupportedPredicate(has.getPredicate());
}
```
In this code, the `containing` predicate is not directly supported, but you
can use `within` or `without` as alternatives to achieve similar functionality.
If you need to check for containment within a list of values, you can use
`within`. If you need to check for non-containment, you can use `without`.
Additionally, according to the `hugegraph-server` documentation, the
`containing` predicate is explicitly listed as unsupported. Therefore, using
the `within` or `without` predicates is a necessary workaround to achieve
similar query functionality. The documentation also lists other unsupported
predicates such as `endingWith`, `startingWith`, and `notContaining`, so be
mindful of these limitations when constructing your queries
