Hi,

Have you check out https://wiki.apache.org/solr/TermVectorComponent, this
request handler can return all term related vectors

Options

   - tv.tf - Return document term frequency info per term in the document.
   - tv.df - Return the Document Frequency (DF) of the term in the
   collection. This can be expensive.
   - tv.positions - Return position information.
   - tv.offsets - Return offset information for each term in the document.
   - tv.tf_idf - Calculates tf*idf for each term. Requires the parameters
   tv.tf and tv.df to be "true". This can be expensive. (not shown in
   example output)
   - tv.all - If true, turn on extra information (tv.tf, tv.df, etc)
   -

   tv.fl - (Solr3.1 <https://wiki.apache.org/solr/Solr3.1>) Provides the
   list of fields to get term vectors for (defaults to fl)
   - tv.docIds - List of Lucene document ids (not the Solr Unique Key) to
   get term vectors for.
