im upgrading our java client from 0.60.2 to 2.2.0. in old version i found BaseQueryBuilder and related functions and i could replace most of the code with QueryBuilder. now im confused about this code segment.

BaseQueryBuilder fq = new BaseQueryBuilder()  
{  
@Override  
protected void doXContent(XContentBuilder builder, Params params) throws IOException  
{  
builder.startObject("multi\_match");  
builder.field("query", matchquery);  
builder.field("fields", new String[] { k });  
builder.field("type", "phrase");  
builder.field("operator", "and");  
builder.endObject();  
}  
};

**how can i replace above code segment with suitable function?**

whole code is  
BoolQueryBuilder query = QueryBuilders.boolQuery();  
BaseQueryBuilder fq = QueryBuilders.fieldQuery(fiedname, quertpattern);  
fq = new BaseQueryBuilder()  
{  
@Override  
protected void doXContent(XContentBuilder builder, Params params) throws IOException  
{  
builder.startObject("multi\_match");  
builder.field("query", quertpattern);  
builder.field("fields",fiedname);  
builder.field("type", "phrase");  
builder.field("operator", "and");  
builder.endObject();  
}  
};

query.must(fq);
