boolean search allocates clauses for all tokens having the prefix or matching the wildcard expression. > Why does it work on small indexes but not > large?

And you need a variant of the query parser that uses these queries. This can be done, even without recompiling lucene, but you will have to do some programming at the level of lucene queries. Shouldn't be hard, since you can use the sources as a starting point. I guess this does not exist because the lucene developer decided to prefer a query error rather than uncomplete results.
