Did not find the ready-made, do it yourself. Reference to the log4net. NOSQL Code.Redis's C # client uses Servicestack

:[20020101 to 20030101]This will look for all documents that meet the Mode_date field in greater than or equal to 20020101, or less than 20030101. Note: Range queries are not dedicated to date fields, and you can also make range queries on non date fields.Title:{aida to Carmen}This will look for documents with all headings between Aida and Carmen but that do not contain Aida and Carmen. Queries that contain the maximum and minimum values use square brackets, excluding the use of curly braces.

Junit 4 allows you to run test classes in bulk by using test suite classes. To create a test suite for a set of test classes, add the following annotations for the test class: @RunWith (Suite.class) @SuiteClasses (Testclass1.class, Testclass2.class) When run, all test classes contained within the @suiteclasses annotation are executed. Junit 4 test suite Sample In this case, Arithmetictest.java and Geometric
