This is an advanced subject, do not attempt without first understanding the other examples of this page. As stated in the official Django Rest Framework on pagination: Pagination is only performed automatically if you're using the generic views or viewsets. If you're using a regular APIView, you...

This example shows you how to implement proxy classes for your Minecraft Mod Application, which are used to initialize your mod. First of all you will need to implement the base CommonProxy.java class which contains the 3 mainly used method: public class CommonProxy { public void preInit(FMLP...

First of all, watch out which analyzer you are using. I was stumped for a while only to realise that the StandardAnalyzer filters out common words like 'the' and 'a'. This is a problem when your field has the value 'A'. You might want to consider the KeywordAnalyzer: See this post around the analyz...

Next, you can either create your query using the QueryParser: See this post around overriding the default operator. // Create a query parser without a default field in this example (the first argument): QueryParser queryParser = new QueryParser("", analyzer); // Optionally, set the d...

Or you can achieve the same by constructing the query yourself using their API: See this tutorial around creating the BooleanQuery. BooleanQuery multiTermQuery = new BooleanQuery(); multiTermQuery.add(new TermQuery(new Term("field_name1", "field value 1")), BooleanClause.Occur...

Then we finally pass the query to the writer to delete documents that match the query: See the answer to this question. See the API here // Remove the document by using a multi key query: // http://www.avajava.com/tutorials/lessons/how-do-i-combine-queries-with-a-boolean-query.html indexWriter....

A is an array and p and q indexes of the array such as you gonna sort the sub-array A[p..r]. B is a sub-array which will be populated by the sort. A call to p-merge-sort(A,p,r,B,s) sorts elements from A[p..r] and put them in B[s..s+r-p]. p-merge-sort(A,p,r,B,s) n = r-p+1 if n==1 ...

Suppose we have a simple class with validation annotations public class UserDTO { @NotEmpty private String name; @Min(18) private int age; //getters/setters } A controller to check the UserDTO validity. @RestController public class ValidationController { @Reque...
