Description

If hl.fl contains commas and whitespaces, e.g. hl.fl=title, content, the PostingsSolrHighlighter produces the following result:

  "highlighting": {
    "mydoc1": {
      "title": [],
      "": [],
      "content": [
        "my highlighted content. "
      ]
    },
    "mydoc2": {
      "title": [],
      "": [],
      "content": [
        "my highlighted content 2. "
      ]
    }
  },

Two things:

• The space followed by the comma leads to an empty field (or even a bunch in case of longer field list).
• Why is "title": [], included in the response (though hl.defaultSummary is not set)?

Tested with Solr 4.10.2.
