json - Elasticsearch: completion sorting by the number of matched documents -

-

i implementing tag autocompleter elasticsearch. tags stored inside indexed documents in various string arrays:

 { ... "skills": {   "industries_solutions": [     "project-management"   ],   "skills_competencies": [     "javascript"   ],   "highlighted": [],   "tag_suggest": {     "input": [       "javascript",       "hibernate",       "project-management"     ]   },   "job_roles": [     "hibernate"   ] } }

as can see, included them in tag_suggest object , mapped in way able query _suggest api kind of queries:

{ "tag_suggest":{     "text":"jav",     "completion": {         "field" : "skills.tag_suggest",         "fuzzy" : {             "fuzziness" : 1         }     } } }

which correctly returns:

    {   "_shards": {     "total": 5,     "successful": 5,     "failed": 0   },   "tag_suggest": [     {       "text": "jav",       "offset": 0,       "length": 3,       "options": [         {           "text": "java",           "score": 1         },         {           "text": "javascript",           "score": 1         }       ]     }   ] }

what able sort results basing on number of matched documents. example, if "java" tag included in 1 document , javascript included in 10 documents, latter appear first suggestion result. nice have number of matched documents, sort of stackoverflow-like. how implement feature? completion correct way go? thank you.

Qt4: how to send QString inside a struct via QSharedMemory -

-
i have struct struct control_data{ int column_number; qstring cell; }; i need send thread of qsharememory. read can't because qstring contains pointers inside. other ways? you have serialize struct byte array. can convert qstring const char* this: mystring.tostdstring().c_str(); but serializing qstring should work. the first step serialize struct qdatastream using qt, example here . then once struct can read , written can pass shared memory. a complete example of using qsharedmemory can found here . here relevant code: // first, test whether shared memory segment attached process. // if so, detach if (sharedmem.isattached()) { sharedmem.detach(); } ... qbuffer buffer; buffer.open( qbuffer::readwrite ); qdatastream out( &buffer ); out << youstruct; int size = buffer.size(); // size of int + size of qstring in bytes if ( !sharedmem.create( size ) ) { return; } // write shared memory sharedmem.lock(); char *to = (char*...

python - jinja2: TemplateSyntaxError: expected token ',', got 'string' -

-
i new jinja2 , having issue using python regular expression (re). in following code bold lines have error string in them. {% block content %} <div class="container"> {% l in lines %} {% if re.search(r"error", l) %} {# <<< throws error #} <b> {{ l }} </b> {% else %} {{ l }} <hr> {% endif %} {% endfor %} </div> {% endblock %} the re.search above throws following error: jinja2.exceptions.templatesyntaxerror templatesyntaxerror: expected token ',', got 'string' raw python code not supported in jinja2 template syntax. {% if re.search(r"error", l) %} replace line with {% if "error" in l %} can fix problem. if logical condition more complicated, should consider defining own custom filters (which can call python code) or complicated things in view layer. go check global namespace .
