Alan Woodward commented on LUCENE-7895:
---------------------------------------

I opened LUCENE-6513 a while back to try and stop the memory blowup caused by 
SpanMTQWrapper, maybe that's worth revisiting?

Prefix ngrams will work for prefix queries, but doesn't generalize, 
unfortunately.

> Add hooks to QueryBuilder to allow for the construction of MultiTermQueries

> QueryBuilder currently allows subclasses to override simple term query 
> construction, which lets you support wildcard querying.  However, there is 
> currently no easy way to override phrase query construction to support 
> wildcards.
