title: solr how to properly use boost factor in a query?
body: <p>Ok, so I am using many fields with qf, like:</p>
  
  <pre><code>[qf] =&gt; frpId^5 fundraise_title^3 fundraiser_display_name^3 charity_name^2 participantFname^2 participantLname^2 participantEmail^1 groupName^3 fundraise_text^ fundraiseTitleExact^15 fundraiserDisplayNameExact^15 charityNameExact^15 participantFnameExact^10 participantLnameExact^10 groupNameExact^10 all^
  </code></pre>
  
  <p>but I really want that exact matches for the field fundraiseTitleExact to be on top.</p>
  
  <p>With this previous set up of qf, they are on the position 32. </p>
  
  <p>Let's say that I am boosting fundraiseTitleExact like:</p>
  
  <pre><code>[qf] =&gt; frpId^5 fundraise_title^3 fundraiser_display_name^3 charity_name^2 participantFname^2 participantLname^2 participantEmail^1 groupName^3 fundraise_text^ fundraiseTitleExact^15000000000000000 fundraiserDisplayNameExact^15 charityNameExact^15 participantFnameExact^10 participantLnameExact^10 groupNameExact^10 all^
  </code></pre>
  
  <p>But even now the fundraiseTitleExact exact match is only on the position 27 (5 positions up) and is not going upper. </p>
  
  <p>How can I prioritise this field over the rest?</p>
