Implementation of fuzzy queries

Discussion about which search fields to be included in the fuzzy search and what's the expected fuzzy behaviour for that particular field.

Note: Using elasticsearch fuzzy queries we can include fuzziness at a max edit distance of 2. That means a maximum of 2 edits between the query and a term in a document is allowed. Eg. "urop" can yield search results the same as "europe" but "urropee" can't as it differs by 3 characters from the original text.
