    Description

      FTS search query in Python 3.x does NOT return fields anymore.

      FTS search query in Python 2.x DOES.

       

      Explanations:

      In 2.x I have the following code :

      from couchbase.cluster import Cluster, PasswordAuthenticator
      from couchbase.fulltext import Params, MatchQuery, PrefixQuery
      import time
      from couchbase.bucket import Bucket
      cluster = Cluster('couchbase://localhost:8091')
      cluster.authenticate(PasswordAuthenticator('Administrator', 'password'))
      a
      # open travel-sample bucket
      cb = cluster.open_bucket('demo2')
      start = time.time()
      it = cb.search('demo2_nGram', PrefixQuery('pari'), fields = ["name"], limit=20)
      a=[]
      for hit in it:
      	print(hit)
      print('Time taken: ', time.time() - start, " seconds")
      

      The field name is actually returned. Result is OK.

      On 3.X (I tested 3.0.1 and 3.0.5, the latest one), corresponding code is:

      from couchbase.cluster import Cluster, ClusterOptions, PasswordAuthenticator
      from couchbase.exceptions import CouchbaseException
      from couchbase.search import QueryStringQuery, SearchQuery, MatchQuery, SearchOptions, PrefixQuery, HighlightStyle, SortField, SortScore, TermFacet
      import time
      cluster = Cluster('couchbase://localhost:8091', ClusterOptions(PasswordAuthenticator('Administrator', 'password')))
      start = time.time()
      result = cluster.search_query('demo2_nGram', PrefixQuery('pari'), fields=['name'], limit=20)
      a=[]
      for row in result.rows():
      	print(len(row.fields))
      	#print(row.score)
      	a.append(row.id)
      print('Time taken: ', time.time() - start, " seconds")
      print(len(result.rows()))
       

      And no fields is returned : len(row.fields) === 0
      I checked in wireshark and I CAN see the fields result in the response returned to the client BUT there is nothing in my row.fields object (empty). Result is NOK.

      Note : I “stored” the fields name and cityname (this one is not used here) in the FTS index definition (see picture in attachment)

            Note : I tried using SearchParams as well (no more success).
