Variable as suffix

[ThomasVer]

When using a variable as a suffix, it doesn't return the JSON you would expect.

For example, this code snippit

var dynamicFields = new List<string> { "private-email", "birthday", "fax" };

...
.Query(searchQuery)
.Type(TextQueryType.CrossFields)
.OnFieldsWithBoost(fb =>
    {
        fb
            .Add(f => f.FirstName, 3.0)
            .Add(f => f.FirstName.Suffix("edge_ngram"), 2.0)
            .Add(f => f.LastName, 3.0)
            .Add(f => f.LastName.Suffix("edge_ngram"), 2.0)
            .Add(f => f.EmailAddress, 3.0)
            .Add(f => f.EmailAddress.Suffix("edge_ngram"), 2.0)
            .Add(f => f.Country.Name, 3.0)
            .Add(f => f.Country.Name.Suffix("edge_ngram"), 2.0)
            .Add(f => f.Country.ISO2, 1.0);

        foreach (string suffix in dynamicFields)
        {
            fb.Add(f => f.DynamicFields.Suffix(suffix), 3.0);
        }
    }
)
...

results in the following JSON (notice the dynamicFields):

...
{
  "type": "cross_fields",
  "query": "demo",
  "fields": [
    "firstName^3",
    "firstName.edge_ngram^2",
    "lastName^3",
    "lastName.edge_ngram^2",
    "emailAddress^3",
    "emailAddress.edge_ngram^2",
    "country.name^3",
    "country.name.edge_ngram^2",
    "country.iSO2^1",
    "suffix.dynamicFields^3",
    "suffix.dynamicFields^3",
    "suffix.dynamicFields^3"
  ]
}
...

Hi @ThomasVer

We can add support for it but it will be slightly slower then without variables since we actually have to compile the Expression once and then execute on it.

We already do this for expressions that take the form of p=>p.Dictionary[field].

Hi @Mpdreamz

Thanks for the feedback.
As a workaround, I am manually creating a list of strings (including the boost factor) and passing that list to the .OnFields() function. This seems to be doing the trick.
