One possibility is to have just a "groups" field with a positionIncrementGap of, say, 100. that is multiValued.
Now, index values like "group1 foo bar happy joy joy" "group2 some more words to search" etc. Now do phrase queries with a slop of less than 100. Then searches like groups:"group1 more"~99 would not match because the gap is greater than the slop. Of course this works better if the values are single tokens and you can index values like group1 foo group1 bar group1 happy group1 joy group2 some with the same increment trick. In that case, the slop could just be, say, 2 and the increment gap 10 or some such.
