MultiCollector

class MultiCollector : Collector

A Collector which allows running a search with several Collectors. It offers a static wrap method which accepts a list of collectors and wraps them with MultiCollector, while filtering out the null ones.

NOTE:When mixing collectors that want to skip low-scoring hits ([ ScoreMode.TOP_SCORES]) with ones that require to see all hits, such as mixing [ TopScoreDocCollector] and [TotalHitCountCollector], it should be faster to run the query twice, once for each collector, rather than using this wrapper on a single search.
