We've covered this a few times in the past (perhaps needs a dedicated help topic!) but let my briefly explain the difference in the [RANGE] command and the Range popup menu.
Technically, they have one specific difference: The Range popup menu limits the search, while the [RANGE] command limits the displayed results. Now, this may seem like a technical distinction, it allows for different searches. Consider:
1) What are all of the words used once throughout Revelation? Answer: [COUNT 1] with Range popup set to Revelation.
2) What are all of the hapax legomenon (the words used once ever) (the words used once ever) in Revelation? Answer: [COUNT 1] AND [RANGE Revelation]
You could even combine them. Such as:
3) List all of the words used once in Luke's writings that occur in the first chapter of Acts? [COUNT 1] AND [RANGE Acts 1] with Range popup set to Luke, Acts.
This distinction also matters when using the different Analytics. If you run a search for [VERB] AND [RANGE Matthew] you'll notice that your Hits Graph still consists of the entire corpus. Thats because the *results* were limited, not the search. To limit the search, and thus the range displayed in the Hits Graph, use the Range popup menu.
Final thought: Remember that the Range popup is available via the '+' button as a Search Condition.
