Solr suggester : duplicate suggestions

[Dhanesh Radhakrishnan]

Dear all,
I'm facing two issues with solr suggester component.

*First *
If I typed "Fire and safety", I'll get the result. But If I type "Fire &
safety" suggester is not showing

*Second*
I'm getting duplicate suggestions  in suggester

 "suggest": {
        "categorySuggester": {
            "software": {
                "numFound": 100,
                "suggestions": [
                    {
                        "term": "Software And Web Development||6070",
                        "weight": 0,
                        "payload": ""
                    },
                    {
                        "term": "Software And Web Development||6070",
                        "weight": 0,
                        "payload": ""
                    },
                    {
                        "term": "Software And Web Development||6070",
                        "weight": 0,
                        "payload": ""
                    }
                    ........
                    ........
                    ........

                ]
            }
        }
    }
