Hi community,

I used algo.unionFind in graph algorithm package for community detection, and got the community detection result.

Here is my code:

```
CALL algo.unionFind('HMGS', 'jaccard', {weightProperty:'jaccard_weight', defaultValue:0.0, threshold:0.03, concurrency: 1, write:true, writeProperty:'cluster'})
```

Here is my community detection result

My problem is I want to visulize the result in neo4j, but I fail.

I want the nodes carrying same set id gathering together.

I did try

```
MATCH (n:HMGS)
WHERE n.cluster
RETURN n
```

This gave me an clienterror

```
Don't know how to treat that as a predicate: Long(0)
```

I am just wondering am I doing right to visulize the community detection result?

Or there is another way to do it?

Thanks for advance

neo4j version: 3.5.14
