Hi there, I don't understand how URI Search are mapped to query string. I read this two links: [https://www.elastic.co/guide/en/elasticsearch/reference/1.6/query-dsl-query-string-query.html](https://www.elastic.co/guide/en/elasticsearch/reference/1.6/query-dsl-query-string-query.html) AND [https://www.elastic.co/guide/en/elasticsearch/reference/current/search-uri-request.html](https://www.elastic.co/guide/en/elasticsearch/reference/current/search-uri-request.htm) I want to try out the two parameters (analyze\_wildcard and allow\_leading\_wildcard) mentioned in link [2](https://www.elastic.co/guide/en/elasticsearch/reference/current/search-uri-request.htm). I don't really know how to use them in the URI search and i think I don't really understand whats the point of this parameters. If I disable the allow\_leading\_parameters and still use a \* in my query, how will ES react? If I use the analyze\_wildcard to true, do it search for every term which is similar without typing \* ? hope you can help me ---
