Hi there,

I just upgraded our [Elasicsearch.NET](http://Elasicsearch.NET) and NEST to 5.4 (from 5.2.2). After doing this some code doesn't work any more. Specifically the .Wildcard on a QueryContainer. I had the following code:

> ```
> var query = value.Contains("*") ? (Func<QueryContainerDescriptor<T>, QueryContainer>)
> (bs => bs.Wildcard(propConfig.KeySelector, value)) : // wildcard search
> (bs => bs.Term(propConfig.KeySelector, value)); // default term search
> 
> ```

On the bs.Wildcard I get the exception:

> The call is ambiguous between the following methods or properties: 'QueryContainerDescriptor.Wildcard(Expression\<Func\<T, object\>\>, string, double?, RewriteMultiTerm?, string)' and 'QueryContainerDescriptor.Wildcard(Expression\<Func\<T, object\>\>, string, double?, MultiTermQueryRewrite, string)'

However I also noticed Wilcard is now deprecated. I however can't find any documentation about this.  
What is the suggested query to use now instead of Wildcard if it is actually deprecated?

Thank you,  
Schoof

Answered this [issue on the github repo](https://github.com/elastic/elasticsearch-net/issues/2805), posting here for posterity.

Hey @anon99430464,

that particular method call for `WildCard()` was deprecated in [NEST 5.3.0](https://github.com/elastic/elasticsearch-net/releases/tag/5.3.0) because of [#2688](https://github.com/elastic/elasticsearch-net/issues/2688).

It's easily resolved by specifying `rewrite` though

```auto
(bs => bs.Wildcard(propConfig.KeySelector, value, rewrite:(MultiTermQueryRewrite)null))

```

The deprecated methods will be removed in the next major release so this won't flag there.
