It will likely stop in the middle of the first segment, and then before collecting further segments. FYI you can not only throw a CollectionTerminatedException from the collect method, but also from the getLeafCollector method, which allows to skip a segment entirely before even starting to find a match. We have such a collector in Elasticsearch, feel free to copy-paste it and adapt to your needs if you want.

For various reasons, we now want to place an upper bound on the number of documents actually collected. Is there a reasonable way to put a limit on the results returned by a SimpleCollector? Or do I need to change Collectors? Based on the docs, I could keep a counter and raise a CollectionTerminatedException after N documents, but then the search moves on to the next leaf. I'd like to have the entire search terminate and return the collected documents. Any assistance for a Lucene novice is greatly appreciated! -Tod Tod Olson <t...@uchicago.edu<mailto:t...@uchicago.edu><mailto:t...@uchicago.edu<mailto:t...@uchicago.edu>>> Systems Librarian Interim Director for Integrated Library Systems University of Chicago Library
