Search

Catalyst Search enables data searching in the indexed columns of the tables in the Data Store. It allows you to perform powerful searches through volumes of data with a single search query.

Search Data in Tables

The search() method is used for searching data in the tables in a specific pattern. Before you execute a search operation, you must construct the search pattern to pass to the search() method, as shown in the code syntax below:

    

        
copy
        

            

        
    
    

         ZCatalystApp.shared.search( searchOptions : ZCatalystSearchOptions, completion : @escaping( Result< [ String : Any ], ZCatalystError > ) -> Void )
    

Parameters:

• searchOptions: The instance of the ZCatalystSearchOptions class to be passed to the search() method.
• completion: If the call executes successfully, the completion block returns the data from the search results. Else, it returns an error.

You can create the instance for searchOptions in the following way:

    

        
copy
        

            

        
    
    

         ZCatalystSearchOptions(searchText: String, searchColumns : [ TableColumns ])
   .add(searchColumns : TableColumns)
   .add(displayColumns : TableColumns)
   .add(sortColumn : String, in table : String)
   TableColumns( tableName : String )
   TableColumns.add( column : String )

    

A sample code snippet of a search execution is shown below:

    

        
copy
        

            

        
    
    

         var searchColumns = ZCatalystSearchOptions.TableColumns( tableName : "EmployeeDetails" ) //Replace this with your table name
  	searchColumns.add( column : "Age" ) 
//Replace this with your column name
	var searchOptions = ZCatalystSearchOptions( searchText : "25", searchColumns : [ searchColumns ] ) 
//Replace this with your search text
	var displayColumns = ZCatalystSearchOptions.TableColumns( tableName : "EmployeeDetails" ) //Replace this with your table name
	displayColumns.add( column : "Age" ) 
//Replace this with your column name
	searchOptions.add(displayColumns: displayColumns)
	ZCatalystApp.shared.search( searchOptions : searchOptions) { ( result ) in
	switch result{
  		case .success( let response ) :
	   print("Response : \( response )")
	  case .error( let error ) :
   	print( "Error occurred >>> \( error )" )
	  }
	}
