 For these reasons ```IKSqlDBContext.CreateQuery<TEntity>``` was introduced to provide the same functionality via Http 1.1.

+### Lexical precedence (v0.7.0)
+You can use parentheses to change the order of evaluation:
+```C#
+await using var context = new KSqlDBContext(@"http:\\localhost:8088");
+
+var query = context.CreateQueryStream<Location>()
+  .Select(c => (c.Longitude + c.Longitude) * c.Longitude);

+SELECT (Longitude + Longitude) * Longitude FROM Locations EMIT CHANGES;

+
+In Where clauses:
+```C#
+await using var context = new KSqlDBContext(@"http:\\localhost:8088");
+
+var query = context.CreateQueryStream<Location>()
+  .Where(c => (c.Latitude == "1" || c.Latitude != "2") && c.Latitude == "3");
+```
+
+```KSQL

+```
+
+Redundant brackets are not reduced in the current version

+### Raw string KSQL query execution (v0.7.0)
+The following examples show how to execute ksql queries from strings:
+```C#

+
+QueryParameters queryParameters = new QueryParameters
+{
