Matches (Lucene 10.5.0 core API)
Description: declaration: package: org.apache.lucene.search, interface: Matches

Package org.apache.lucene.search

# Interface Matches

All Superinterfaces:
  `Iterable<String>`

All Known Implementing Classes:
  `NamedMatches`

public interface Matches extends Iterable<String>
Reports the positions and optionally offsets of all matching terms in a query for a single document

To obtain a `MatchesIterator` for a particular field, call `getMatches(String)`. Note that you can call `getMatches(String)` multiple times to retrieve new iterators, but it is not thread-safe.

WARNING: This API is experimental and might change in incompatible ways in the next release.
