I sometimes find it helpful to think of the query parts as applying
'filtering' logic, helping to understand how query components play together
in determining the acceptable set of results (mostly ignoring scoring here,
which would usually sort the candidate results).
Consider a set of 10 douments

Hi Tom,
The query you want is
name:[A TO C] name:[G TO K]
(each clause being SHOULD, or put another way, an implicit "OR" in between.
The problem may be how you analyze the name field... is it tokenized at all?
If so, you might be matching on first, last, and middle names, and the

values in a field that is not continuous.
For an example, say I want to find all people with last names
starting with A-C, and G-K.
If I use MUST on each element of the range, then I get nothing. This
