I have a set of documents consisting of unstructured text with an "Entities" attribute. This attribute contains a list of entities which were extracted from the unstructured text by an entity extractor.

When performing aggregations on this "Entities" field, I noticed that the same word will be repeated if it has a different case e.g. Washington and WASHINGTON will both appear

What should I do to just display an entity regardless of the difference in case?  
Or is there a way to standardise the cases?

Also, does Aggregations work on analysed text or does it only work on keyword fields?
