Hi ,
Can any one explain how to search for special characters
in elastic search?
I am using standard analyzer for indexing and searching.
For example in elastic search a field have a value @. if i
search like "_text:@" means i am getting the results of 0 documents.
Standard analyzer, uses standard tokenizer, which splits words at
punctuation characters, removing punctuation.

Correct. For very fine grained and explicit control you may want to
check out the pattern analyzer.

Can you explain the scenario of pattern analyzer. Is it possible to
search like below example using pattern analyzer? I need to find the
exact path in these....
For example path field contains the list of values like,
C:\Users\sample\data\test files\
C:\Users\sample\data\test files\sample data\sample.csv

Read up on the analysis process:
http://www.elasticsearch.com/docs/elasticsearch/index_modules/analysis/
Here are the specific details on pattern analyzer:
http://www.elasticsearch.com/docs/elasticsearch/index_modules/analysis/analyzer/pattern/
The docs do a much better job explaining than I can.
Bottom line, though, the answer to your question depends on how you
want to search the data.
