Hello everyone,
I have follow index mapping:
curl -XPUT 'http://localhost:9200/some\_content/' -d ' { "settings":{ "query\_string":{ "default\_con":"content", "default\_operator":"AND" }, "index":{ "analysis":{ "analyzer":{ "en\_analyser":{ "filter":["snowBallFilter"], "type":"custom", "tokenizer":"standard" } }, "filter":{ "en\_stopFilter":{ "type":"stop", "stopwords\_path":"lang/stopwords\_en.txt" }, "snowBallFilter":{ "type":"snowball", "language":"English" }, "wordDelimiterFilter":{ "catenate\_all":false, "catenate\_words":true, "catenate\_numbers":true, "generate\_word\_parts":true, "generate\_number\_parts":true, "preserve\_original":true, "type":"word\_delimiter", "split\_on\_case\_change":true }, "en\_synonymFilter":{ "synonyms\_path":"lang/synonyms\_en.txt", "ignore\_case":true, "type":"synonym", "expand":false }, "lengthFilter":{ "max":250, "type":"length", "min":3 } } } } }, "mappings":{ "docs":{ "\_source":{ "enabled":false }, "analyzer":"en\_analyser", "properties":{ "content":{ "type":"string", "index":"analyzed", "term\_vector":"with\_positions\_offsets", "omit\_norms":"true" } } } } }'
and I posted the next content:
curl -XPOST [http://localhost:9200/some\_content/docs/](http://localhost:9200/some_content/docs/) -d '
{
"content" : "Some sampling text formatted for text data"
}'
When I make this one request:
_[http://epbyvitw0052:9200/some\_content/docs/\_search?q=sampling](http://epbyvitw0052:9200/some_content/docs/_search?q=sampling)_
I'm getting result:
{
"took": 1,
"timed\_out": false,
"\_shards": {
"total": 1,
"successful": 1,
"failed": 0
},
"hits": {
"total": 1,
"max\_score": 0.095891505,
"hits": [
{
"\_index": "some\_content",
"\_type": "docs",
"\_id": "saLfx6PYR82YR69je0JbAA",
"\_score": 0.095891505
}
]
}
}
but when I send request without type:
_[http://epbyvitw0052:9200/some\_content/\_search?q=sampling](http://epbyvitw0052:9200/some_content/_search?q=sampling)_
then I'm getting nothing:
{
"took": 1,
"timed\_out": false,
"\_shards": {
"total": 1,
"successful": 1,
"failed": 0
},
"hits": {
"total": 0,
"max\_score": null,
"hits": []
}
}
although, I can make the next request with term:
_[http://epbyvitw0052:9200/some\_content/\_search?q=sampl](http://epbyvitw0052:9200/some_content/_search?q=sampl)_
the system found it:
{
"took": 1,
"timed\_out": false,
"\_shards": {
"total": 1,
"successful": 1,
"failed": 0
},
"hits": {
"total": 1,
"max\_score": 0.095891505,
"hits": [
{
"\_index": "some\_content",
"\_type": "docs",
"\_id": "saLfx6PYR82YR69je0JbAA",
"\_score": 0.095891505
}
]
}
}
It's issue appear when I put snowball filter into analyzer.
Could you explain why the system has such behavior?
May be I do something wrong.

In the beginning, I thought a cause is sitting of analyzers, but I have
this issue when I put other stemmers. If I don't use any stemmers the
request _[http://epbyvitw0052:9200/some\_content/\_search?q=sampling](http://epbyvitw0052:9200/some_content/_search?q=sampling)_
returns me necessary index. I think it's problem with implementation of
adding some stemmers.
