Solr search response Order : token position based

Question

I want search results document in sorted order of matched token position

example: I have following docs:

     1. indian institute of technology
     2. cultural arts institute
     3. institute of Management
     4. institute of Arts


search query : ins*
localhost:6983/solr/ts/select?fl=name&indent=true&q.op=OR&q=name%3Ains*

Expected response : 

     3. institute of Management  ----> (institute position ->1)
     4. institute of Arts        -----> (institute position ->1)
     1. indian institute of technology --> (institute position ->2)
     2. cultural arts institute   ------> (institute position ->3)

file : managed-schema

  <fieldType name="single_keyword" class="solr.TextField" positionIncrementGap="100">
    <analyzer type="index">
    <tokenizer class="solr.ClassicTokenizerFactory"/>
    <filter class="solr.LowerCaseFilterFactory"/>
    </analyzer>
    <analyzer type="query">
    <tokenizer class="solr.ClassicTokenizerFactory"/>
    <filter class="solr.LowerCaseFilterFactory"/>
    </analyzer>
  </fieldType>

Debug reference : 
http://localhost:6983/solr/ts/select?fl=name&indent=true&q.op=OR&q=name%3Ains*&debug=true

"rawquerystring": "name:ins*",

"institute_2029": "\n1.0 = name:ins*\n"
},

I Have tried this with autoSugest but it doesn't serve my use case, drawback of using autosuggest: unable to run filter on multiple value and field, unable to return multiple fields in response

There may be an easier way to accomplish what you want, but this could definitely be handled using a a custom scorer. This blog explains the process of creating a custom scorer and outlines other angles through which you may be able to tackle this issue
