      On a schema like the following:

      { _id : ObjectID, description: String}

      With an index like:

      { fields: { 'description': 'text' } }

      Doing this with $and query succeeds as expected:

      db.products.find({$and:[{$text: {$search : 'box'} }, {search:'Box'}] );

      But this query fails:

      db.products.find({$or:[{$text: {$search : 'Bob'} }, {search:'Bob'}] );

      With this error

      $err" : "Runner error: BadValue error processing query: ns=unit_test.products limit=0 skip=0
Tree: $or
description== \"Bob\"
TEXT : query=Bob, language=, tag=NULL
Sort: {}
Proj: {}
planner returned error: Failed to produce a solution for TEXT under OR - other non-TEXT clauses under OR have to be indexed as well.",
"code" : 17144

      (I realize this seems asinine, but my actual code is quite a bit more complicated with a full-text index on several different text fields.)
