SolrJ Text Tagger

This provides extensions to SolrJ for using SolrTextTagger.

Intended Usage

String content; //The content to tag

//NOTE: TaggerParams can be reused for multiple requests
TagParams params = new TagParams();
params.setOverlaps(Overlaps.LONGEST_DOMINANT_RIGHT);
params.setFields("id", "title", "cat");

TagRequest request = new TagRequest(params, 
    new StringStream(content, "text/plain"));
//request.setPath("/my-custom-tagger-path"); //default is "/tag"
//request.setDocIdField("my-id"); //set the name of the `uniqueKey` field if != "id"
try {
    TagResponse response = request.process(client);
    for(Tag tag : response.getTags()){
        int start = tag.getStart();
        int end = tag.getEnd();
    String mention = content.subString(start, end);
        for(SolrDocument doc : tag.getDocs()){
            String title = (String)doc.getFirstValue("title");
            String cat = (String)doc.getFirstValue("cat");
        }
    }
} catch (SolrServerException e) {
    //TODO: Error Handling
