 ## TypeComposer from Elastic mapping
-In other side this module is a plugin for [graphql-compose](https://github.com/nodkz/graphql-compose), which derives GraphQLType from your [elastic mapping](https://www.elastic.co/guide/en/elasticsearch/reference/current/mapping.html) generates input fields for all available methods in QueryDSL, Aggregations, Sorting with field autocompletion according to types in your mapping (like query dev tool in Kibana).
+In other side this module is a plugin for [graphql-compose](https://github.com/nodkz/graphql-compose), which derives GraphQLType from your [elastic mapping](https://www.elastic.co/guide/en/elasticsearch/reference/current/mapping.html) generates tons of types, provides all available methods in QueryDSL, Aggregations, Sorting with field autocompletion according to types in your mapping (like Dev Tools Console in Kibana).
 
-Generated TypeComposer has several awesome resolvers:
-- `search` - greatly simplified `search` method. According to GraphQL adaptation and its projection bunch of params setup automatically due your graphql query.  
-- `searchConnection` - `search` method that implements Relay Cursor Connection [spec](https://facebook.github.io/relay/graphql/connections.htm) for infinite lists. Internally it uses cheap [search_after](https://www.elastic.co/guide/en/elasticsearch/reference/current/search-request-search-after.html) API. One downside, Elastic does not support backward scrolling, so `before` argument will not work.
