Wildcards elasticsearch results

[EugenioCorso]

Need to modify the results found with the search in order to include also sub strings
Example:
Search: el --> Result found: Hello

The description is not very self explanatory. This may really depend on many different aspects like, for example, the token length, the query (using wildcards?) etc. Let's try to dissect the problem a bit more and then try to find a solution, thanks

The choice made was to split every string associated to a record in tokens, e.g. the tokens associated to the string "Hello world" are "Hello" and "world". This tokens are used (in a case insensitive way) to search the results given to the user. The substrings are non matched, e.g. "ell" will not match "Hello". This seem to be a good approach so far

Are we sure that we don't want substrings to be matched? I believe that is a nice to have feature.

As decided, we don't want wildcards search for now but we will see in a next iteration how to proceed.
