We have a suggestion engine and we only auto-complete from 3
characters (or a number).

What would be nice for your case and maybe for ours is that this
expansion done in PrefixQuery is made more explicit so that one
could stop it somewhere or filter it.
I couldn't find sufficient methods in the IndexReader for this but I
didn't look eternally either.
One of the reasons I had for this was to try to do the same as prefix-
matching for span-queries.
(the order and coverage being important if you input a sentence)

We are trying to implement a Google finance-like suggest as you type
search field. The index is quite large and comprised of multiple
fields
to search across so our initial implementation was to use a
BooleanQuery
with multiple PrefixQuery across each field. We quickly ran into the
TooManyClauses exception and are looking for alternatives.
Is there an implementation pattern for this use case using lucene?
This
seems like a common feature on various sites and I'm wondering if
lucene
can be used to support this.
