-----------------------------------------
bq. > Span*Query api is a perfect example.
bq. Can you describe the limitations here in more detail?
Take a look at SpanNearQuery and SpanOrQuery.
1. They don't provide incremental construction (i.e. add() method, like in
BooleanQuery), and they can be built only from an array of subqueries. So, if
you don't know exact amount of subqueries upfront, you're busted. You have to
use ArrayList, which you convert to array to feed into SpanQuery, which is
converted back to ArrayList inside!!
2. They can't be edited. If you have a need to iterate over your query tree and
modify it in one way or another, you need to create brand new instances of
Span*Query. And here you hit #1 again, hard.
3. They can't be even inspected without creating a new array from the backing
list (see getClauses).
I use patched versions of SpanNear/OrQueries, which still use backing
ArrayList, but accept it in constructor, have utility 'add' method and
getClauses() returns this very list, which allows for zero-cost inspection and
easy modification if the need arises.
