Index not found with unique index query

We get

```
Could not find a suitable index to answer graph query and graph scans are disabled: [(com.bio4j.model.uniprot.UniprotGraph.FeatureTypeType.name = compositionally biased region AND label = com.bio4j.model.uniprot.UniprotGraph.FeatureTypeType)]:VERTEX
```

It could be something about spaces and the like.
