java - Spring mongo adding criteria to and operator dynamicaly -

-

I am trying to create dynamic queries with user input and with operation, my code is created. : list & lt; Criteria & gt; Criterias = new ArrayList & lt; Criteria & gt; ();

And add criteria to this list. And successfully adding it successfully now I want to create and operator between each criterion. 

  Criteria = new criteria (). And operators (criterias.get (0), criterias.get (1));   
 This works fine but my input is not correct so I should add it dynamically, I tried  
  for (int I = 0; i & lt; Criterias.size (); i ++) Criteria Criteria = new criteria (). And operator (criterias.get (i));   
 Where am I missing?   
 
 
 A list of benchmarks by "$ and" operator to unite all the standards:  
  Criteria = new criteria (). And Operator (Criterion Toura (New Criterion [Criterion (. ())));

I tried loading the Arial font and it loads successfully but again I get square blocks instead of characters. I import matplotlib.font_manager FM PROP = FM Font Properties (fname = '/ usr / share / fonts / truetype / msttcorefonts / Arial.ttf') And then to display the string I u'Î? ? I ?? Î¿Ï ??

c# - LINQ to Entities does not recognize the method 'Int32 IndexOf(System.String, System.StringComparison)' method -

I have performed a linq query using Entityframework as below GroupMaster getGroup = Null; GetGroup = DataContext.Groups.FirstOrDefault (item = & gt; keyword.IndexOf (item.Keywords, StringComparison.OrdinalIgnoreCase)> = 0 & amp; amp; item.ISNAmd) I found an exception like the method when executing it LINQ units do not recognize the 'Inter 32 index of (system string, system. String compromise)' method, and This method can not be translated to Store expression. Includes () method is sensitive by default, then I need to convert to minimize. Is there any method in which a string match match is examined and whether there is any method to solve the index question of the method? You actually have four options Databases globally Change the colon of it can be done in many ways, a simple Google search should reveal to them. Change the mix of individual tables or columns. Use a stored procedure and specify the call statement on your query Perform...
