 Here is my previous post related to map contains method.  How contains key method works ? Does it allow partial matches or exact matches ? We know map contains key method is case sensitive. if you are create a key using First Name , Last Name and DOB to find unique Account record then system will consider 2 different record for below scenario. 1. First Name - "Capital"  Last Name- "Testing" DOB- 01/01/1989 2. First Name - "CAPITAL" Last Name - "TESTING" DOB- 01/01/1989 The work wound is  map<String,Account> map_Name_Acc = new map<String,Account>(); String sKey = ''; for(Account acc:[SELECT firstname,Lastname,DOB__c from Account limit 10]{      sKey = acc.FirstName+'_'+ acc.LastName+'_'+acc.DOB__c; // this will create duplicate records since key is case sensitive  sKey = acc.FirstName.toLowercase()+'_'+ acc.LastName.toLowercase()+'_'+acc.DOB__c;  } toLowercase() - convert name to lower case, ...

 This is a bug in split function, it does not work for '*'  or '+'.  We will get runtime error. System.StringException: Invalid regex: Dangling meta character '*' near index 0 *  String sBody = '*   Building Name:Brookwood Gardens  *   Is your unit isolated with barrier systems in place?Yes  *   Does your unit have its own supplies?Yes  *   Does your unit have any additional infection control equipment?HVAC filters: YesUVC lights: Yes'; List<String> strList = sBody.split('*'); // This will throw error. system.debug('strList '+strList); Solutions:  List<String> strList =sBody.split('\\*');  // This will solve.
