Team,

Please help me, I am using same max expansion and same ES Query on Elastic versions 6.6 and 8.4, with same set of data. but giving different results.

so, can some one clearly confirms what is the major difference in the latest version.

Query

```auto

"multi_match": {
            "fields": [
              "names"
            ],
            "max_expansions": 5,
            "query": "cur",
            "type": "phrase_prefix"
          }

```

Version : 8+ its giving results {"john curtain","john curpa"}  
version : 6.6 - no data returning.

NOTE : phrase prefix is not working as expected in 6.6 version

can any one confirm the differences of behavior.
