   Hi @wu-sheng , 
   - common tags:
   1. status :  status of response.
   2. qtime : solr 
   
   - query tags
   1. qt: Query Type - which Request Handler should handle the request.
   2. numFound : the numer of SolrDocuments returned from a search.
   3. db.statment: If it enable, span will trace the query parameters of query. (Default disable)
   
   - insert tags(/update/ADD)
   1. docsSize: the number of committed documents.
   2. commitWithin: the time horizon by which the document should be committed
   
   - delete tag(/update/DELETE_X)
   1. delete.by : deletes a list of documents by doc_id. (or deletes documents base on query)
   
   - commit tags (/update/COMMIT) 
   1. softCommit : Performs an explicit commit, causing pending documents to be committed for indexing.
   
   - optimize tags (/update/OPTIMIZE)
   1. maxOptimizeSegs : optimizes down to at most this number of segments
   
   On commit/optimize request,maybe need to trace waitFLush and waitSearch. They explain whether QTime is available. 
   
   About `DB_INSTANCE`, for solr, to get this is expensive and useless.
   About `db.statement`, it will be encode by URLEncoder. I have not idea whether to decode it.
