I am upgrading the elastic search from v2.3.3 to v5.6.2. I am facing the error: Cannot resolve symbol: lowercaseExpanedTerms(boolean).

Below is the line of code where the error occurs:

queryStringQueryBuilder = valueTypeEnum == SearchCriteria.ValueTypeEnum.STRING\_NOT\_ANALYZED ?  
queryStringQueryBuilder.lowercaseExpandedTerms(false) : //cannot find symbol  
queryStringQueryBuilder.analyzer(ANALYZER);

Please help 🙂

After following the discussion on github for this commit, developers have stated that Lucene will take care of whether or not the terms to be converted into lowercase.

So i think that having the line below will have same impact as the old code-  
queryStringQueryBuilder=queryStringQueryBuilder.analyzer(ANALYZER);

instead of the below old code-  
queryStringQueryBuilder = valueTypeEnum == SearchCriteria.ValueTypeEnum.STRING\_NOT\_ANALYZED ?  
queryStringQueryBuilder.lowercaseExpandedTerms(false) : //cannot find symbol  
queryStringQueryBuilder.analyzer(ANALYZER);

Please suggest, if there is something else that can be done or if I am missing something.  
Please help 🙂
