{
"valueCount": 0,
"value": "string",
"field": {
"name": "string"
},
"key": {
"name": "string"
}
}
],
"numFound": 0
}

2. 
   Using *org.springframework.data.solr.core.SolrTemplate * implement search request to Solr using parameters from response
   

Task 3 - Implement autosuggestions (1 Point)

1. 
   Implement API endpoint which is returning array of suggestions:
   

GET api/v1/book/suggest?query=

2. 
   Create suggest field in scheme using org.springframework.data.solr.core.SolrTemplate which is filled from Book.title & Book.authors
   
3. 
   Add required searchComponent and requestHandler for suggestions to solrconfig.xml
   
4. 
   Using org.apache.solr.client.solrj.SolrClient execute suggest query
