[Feature] Filter by enumerated properties in the .net SDK [FIND-13264]

[lounge]

Is your feature request related to a problem? Please describe.
Is there a way to filter enumerated properties in the Where method of the .net SDK. In the docs it states only four filter options:

There are four implementations of IFilterOperator:

NumericFilterOperators: The filter operators for the Number field type. Optimizely Graph supports integer and float type.
BooleanFilterOperators: The filter operators for the Boolean field type.
DateFilterOperators: Filter operators for the DateTime field type.
StringFilterOperators: Filter operators for the String field type.

What we want to do is filter out content based on a list of Geta Categories.

Describe the solution you'd like
A way to filter content based on enumerated properties like a list of int or string.

Describe alternatives you've considered
We have considered querying with native graphQL queries directly with something like StrawberryShake. But it would be nice to have this feature in the .net SDK

Thanks for this request @lounge and sorry for the late response.
If you just need to filter content based on enumerated properties like a list of int or string, we're currently supported it in FilterExtension by using EPiServer.ContentGraph.Extensions. Lets try like this: .Where(x=>x.EnumerableOfStrings.Like("something")).
We're now trying to support IEnumerable of the complex type.

Hi @lounge,
For dealing with IEnumerable properties, I've a blog post https://world.optimizely.com/blogs/manh-nguyen/dates/2024/4/optimizely-graph-client-dealing-with-cms-data-models-for-query-builder/ to show the easiest way to work.
I've also added new methods for allowing filters on IEnumerable of a complex type on version Optimizely.Graph.Client1.3.0, please install new version to try.
For example:
.Where(x=> x.EnumerableField, x=>x.PropertyOfComplexType.Like("demo"))
Please visit docs https://docs.developers.optimizely.com/platform-optimizely/v1.4.0-optimizely-graph/docs/where-filter for more details (maybe you should wait a few days for the documentation to be public).
Feel free to open new Issues if you need anything else or open a discussion if you have questions about this.
