I created a percolator index with custom analyzer ( tokenizer : Whitespace ). But while i applying my docs to that percolate index my custom analyzer is not reflecting . Somewhere in net i read that while searching through percolate also we need to add custom analyzer into that query, So i tried that's too but i got error only ..
it ll be helpful if anyone send that syntax.. or clarify my doubt !!!
