hi
i want to know how to implement fuzzy search for match/match\_phrase/match\_phrase\_prefix in elasticsearch6.8? previously i implement it using below clause in es5.4
"match" : {
"\_all" : {
"query" : "test",
"operator" : "and",
"boost" : 1,
"fuzziness" : 0.75,
"prefix\_length" : 0,
"max\_expansions" : 100
}
}
but in es6.8, i use below clause to implement it
{
"multi\_match" : {
"query" : "test",
"type" : "phrase",
"boost" : 1,
"fuzziness" : 0.75,
"prefix\_length" : 0,
"max\_expansions" : 100
}
}
but search meet with below exception:
{"error":{"root\_cause":[{"type":"parsing\_exception","reason":"Fuzziness not allowed for type [phrase]"
any solution can solve the problem for it? or other method? thanks`Preformatted text`

why are you using `type: phrase` in the 6.8 example, but not in the 5.4 example? Those end up being two different queries. Also one is a `match` query and one if a `multi_match` query and the `operator` is different as well. Those will end up as very different queries being executed, so I am wondering if you are trying to create a new query or resemble the behaviour of the old query.
Also the `_all` field has been disabled by default in 6.x.

`because _all field is disabled, so i can't use match combining with _all, but i want to search all documents that crawling mongodb collection's fields with value to elasticsearch's index, i try multi_match to combine phrase search without fuzziness, it's ok and search effect is same as using match combine _all for es5.4, but es6.8 don't support phrase with fuzziness`

Why don't you either enable the all field again or use the workaround described in the deprecation warning at [https://www.elastic.co/guide/en/elasticsearch/reference/6.8/mapping-all-field.html](https://www.elastic.co/guide/en/elasticsearch/reference/6.8/mapping-all-field.html) ?

`i have adopt the multi_match solution, whether _all field also can be enabled in elasticsearch7 and above version? because later i also need to upgrade to es7, except for this all field workaround, do i have other option for it?`

please take the time to read my last message and the included link, where I explicitely mentioned a workaround that is laid out in the documentation, as this exact feature is removed in 7.0 but can be rebuild in a different manner.
