Lucene Search in Umbraco searches for only lower case words or Lucene search is case sensitive in umbraco

From few days i was working on lucene search in umbraco. I did everything properly ie. copied latest dll files, did indexing , made user control for search but still it was not working fine .

After searching for about a day i found that lucene search by default converts the "search word" in to lower case & then searches for the word in the website.Due to this if i have same word with upper case in my website then it will not be filtered & shown in search result.

The solution is very much simple for this , just we have to change "analyzer" attribute in the
ExamineSettings.config file which will be in config folder of the umbraco website.

you will find that your indexer & Searcher will be having attribute "analyzer" something like this...

analyzer="Lucene.Net.Analysis.WhitespaceAnalyzer, Lucene.Net" 

Just you have to change analyzer to this....

analyzer="Lucene.Net.Analysis.Standard.StandardAnalyzer, Lucene.Net" 

save the file & then publish your all nodes ...
try searching with uppercase after this .... it will work the way you want ....

Hope it Helps ......
