Dawid Weiss updated LUCENE-10539:
---------------------------------
Summary: Return a stream of completions from FSTCompletion (was: return a
stream of completions from FSTCompletion)
> Return a stream of completions from FSTCompletion
> -------------------------------------------------
>
> Key: LUCENE-10539
> URL: https://issues.apache.org/jira/browse/LUCENE-10539
> Project: Lucene - Core
> Issue Type: New Feature
> Reporter: Dawid Weiss
> Assignee: Dawid Weiss
> Priority: Minor
>
> FSTLookup currently has a "num" parameter which limits the number of
> completions from the underlying automaton. But this has severe disadvantages
> if you need to collect completions that need to fulfill a secondary condition
> (for example, collect only verbs or terms that contain a certain infix). Then
> you can't determine the 'num' parameter easily because the number of filtered
> completions is unknown.
> I also think implementation-wise it's also much nicer to provide a stream
> that iterates over completions rather than a fixed-size list. This allows for
> much more elegant code (stream.filter, stream.limit).
> The provided patch adds a single {{Stream<Completion> lookup(key)}} method
> and modifies the existing lookup methods to use it.
