title: User defined termvectors in ElasticSearch
body: <p>How (if at all possible) can one insert any term-vector in an ElasticSearch index?</p>
  
  <p>ES computes term-vectors, behind the scenes, in order to carry out it's text mining tasks, but it would be useful to be able to enter any list of (term, weight) pairs instead.</p>
  
  <p>Why?</p>
  
  <p>Well, for instance, though ES enables kNN (k-nearest-neighbors) for k=2, in the context of geographic proximity, it doesn't have any explicit k>2 functionality. If we were able to insert our own term-vectors, we could hack a k>2 functionality by harnessing ES's built in text-indexing methods.</p>
  
  <p>Any indications on this issue?</p>
