The phrase query allows to query for exact term phrases in the index. The provided terms must exist in the correct order, at the correct index offsets, in the specified field (as no analyzer are applied to the terms). Queried field must have been indexed with includeTermVectors set to true. It is generally more useful in debugging scenarios, and the Match Phrase Query should usually be preferred for real-world use cases.
