I am working on Elasticsearch migration from 1.7.1 to 5.0.  
I fixed most of the issues in the code after upgrading to 5.0 but I couldn't figure out how to change **_FilterContainer_** to work in new version.

Below is my code

```
 public static List< **FilterContainer** > GetPriceRangeFilters(SearchListCriteria criteria, out List< **FilterContainer** > additionalpricefilters)
        {
            var pricefilters = new List< **FilterContainer** >();
            additionalpricefilters = new List< **FilterContainer** >();
            if (criteria.SearchGlobalSettings.MinimumPriceRange != null && criteria.SearchGlobalSettings.MinimumPriceRange.Length > 0)
            {
                const string fieldName = "itemPrices.webPrice";
                pricefilters.Add((new **FilterDescriptor** <ItemSearchEntry>()).Query(a => a.Range(n => n.OnField(fieldName).GreaterOrEquals(criteria.SearchGlobalSettings.MinimumPriceRange[0].ToString()).
                    LowerOrEquals(criteria.SearchGlobalSettings.MaximumPriceRange[0].ToString()))));
                for (var i = 1; i < criteria.SearchGlobalSettings.MinimumPriceRange.Length; i++)
                {
                    additionalpricefilters.Add((new **FilterDescriptor** <ItemSearchEntry>()).Query(a => a.Range(n => n.OnField(fieldName).
                        GreaterOrEquals(criteria.SearchGlobalSettings.MinimumPriceRange[i].ToString()).LowerOrEquals(criteria.SearchGlobalSettings.MaximumPriceRange[i].ToString()))));
                }
            }
            return pricefilters;
        }
```

`FilterContainer` no longer exists in NEST 2.0 onwards, [because filters and queries merged in Elasticsearch into queries](https://www.elastic.co/guide/en/elasticsearch/reference/2.4/breaking_20_query_dsl_changes.html#breaking_20_query_dsl_changes), with a _query_ or _filter_ context.

Where you would have used `FilterContainer`, use `QueryContainer` and then when adding to the search, pass the collection of `FilterContainer` into a `bool` query `filter` clause.

I was able to convert filter containers to Query containers. Still working on indexing issues. Thanks for your help.
