### Description Hello, I'm new to Lucene, so I apologize if this is expected behaviour. I've noticed current implementation of `PhraseQuery#rewrite` does not take into account fuzziness (`slop`) when transforming single-term `PhraseQuery` to `TermQuery`. This can be seen here: https://github.com/apache/lucene/blob/main/lucene/core/src/java/org/apache/lucene/search/PhraseQuery.java#L287 . But also with these examples (last example is what's questionable to me): | Raw query (parameter of `parse`) | Parsed query (`toString` output) | Note | |--------|--------|--------| | `A:12345` | `A:12345` | return value is `TermQuery(A:12345)` | | `A:12345~1` | `A:12345~1` |return value is `FuzzyQuery(A:12345~1)` | | `A:"12 345"~1` | `A:"12 345"~1` |return value is `PhraseQuery(A:"12 345"~1)` | | `A:"12345"~1` | `A:12345` |return value is `TermQuery(A:12345)` | In last example, notice the disappearance of fuzziness. I see two alternatives that seem more correct than this: 1. `PhraseQuery(A:"12345"~1)` 2. `FuzzyQuery(A:12345~1)` In my understanding, 1st option seems correct. For example, if we imagine a document `{ "A": "12345 6789" }`, 1st option wouldn't match it while 2nd option would, and intention of original query was to not match it (because it was written as `PhraseQuery`). All examples are tested with: `new StandardQueryParser(new StandardAnalyzer()).parse(query, "A")`, and `toString()` output is pasted here. I'm open to contributing a fix for this (including unit tests). This also seems the case for `MultiPhraseQuery`, but I'm not 100% sure as I've never used it. Thank you for amazing product. ### Version and environment details Lucene version: 10.0.0 OS: Arch Linux JDK: 21 -- This is an automated message from the Apache Git Service.
