Sorry, I'm really new to elasticsearch...
I'm trying basic functionalities...
I created my first index (to be used for italian language):
```auto
PUT index_it
{
"settings": {
"analysis": {
"filter": {
"italian_elision": {
"type": "elision",
"articles": [
"c",
"l",
"all",
"dall",
"dell",
"nell",
"sull",
"coll",
"pell",
"gl",
"agl",
"dagl",
"degl",
"negl",
"sugl",
"un",
"m",
"t",
"s",
"v",
"d"
],
"articles_case": true
},
"italian_stop": {
"type": "stop",
"stopwords": "_italian_"
},
"italian_keywords": {
"type": "keyword_marker",
"keywords": [
"esempio"
]
},
"italian_stemmer": {
"type": "stemmer",
"language": "italian"
}
},
"analyzer": {
"italian_full": {
"tokenizer": "standard",
"filter": [
"italian_elision",
"lowercase",
"italian_stop",
"italian_keywords",
"italian_stemmer"
]
}
}
}
}
}
{
"acknowledged": true,
"shards_acknowledged": true,
"index": "index_it"
}
```
and put one word in index ("torta", Italian for "cake"):
```auto
PUT index_it/_doc/1
{
"title": "torta"
}
{
"_index": "index_it",
"_id": "1",
"_version": 1,
"result": "created",
"_shards": {
"total": 2,
"successful": 1,
"failed": 0
},
"_seq_no": 0,
"_primary_term": 1
}
```
If I analyze that word, I see it's correclty "stemmed" as "tort":
```auto
POST index_it/_analyze
{
"analyzer": "italian_full",
"text": "torta"
}
{
"tokens": [
{
"token": "tort",
"start_offset": 0,
"end_offset": 5,
"type": "",
"position": 0
}
]
}
```
I'd expect to be able to search for both "torta" and "torte" (same word, plural).
I can find the singular form, but not the plural... :-/
```auto
GET index_it/_search
{
"query": {
"match": {
"title": "torta"
}
}
}
{
"took": 6,
"timed_out": false,
"_shards": {
"total": 1,
"successful": 1,
"skipped": 0,
"failed": 0
},
"hits": {
"total": {
"value": 1,
"relation": "eq"
},
"max_score": 0.2876821,
"hits": [
{
"_index": "index_it",
"_id": "1",
"_score": 0.2876821,
"_source": {
"title": "torta"
}
}
]
}
}
```
But not "torte":
```auto
GET index_it/_search
{
"query": {
"simple_query_string": {
"fields": ["title"],
"query": "torte"
}
}
}
{
"took": 0,
"timed_out": false,
"_shards": {
"total": 1,
"successful": 1,
"skipped": 0,
"failed": 0
},
"hits": {
"total": {
"value": 0,
"relation": "eq"
},
"max_score": null,
"hits": []
}
}
```
What do I miss? Shoul I specify the analizer in the queryes too?

Hi Marco and welcome to the Elastic community!
You are on the right track, but in order for the `title` field to be analyzed with the `italian_full` analyzer (and support stemming in Italian), you need to explicitly specify that in the field's mapping when you create the index:
```auto
PUT index_it
{
"settings": { ... }, // your settings as above
"mappings": {
"properties": {
"title": {
"type": "text",
"analyzer": "italian_full"
}
}
}
}
```
This configures two things: 1. `title` will be analyzed with `italian_full`, rather than with the default analyzer, and 2. queries against `title` will also be analyzed with `italian_full`, so you can run searches in Italian.
```auto
PUT index_it/_doc/1
{
"title": "torta"
}
GET index_it/_search
{
"query": {
"match": {
"title": "torte"
}
}
}
{
...
"hits": [
{
"_index": "index_it",
"_id": "1",
"_score": 0.2876821,
"_source": {
"title": "torta"
}
}
]
}
```
For more info, please check out [this guide](https://www.elastic.co/guide/en/elasticsearch/reference/current/specify-analyzer.html) on specifying an analyzer.
If you want the Italian analyzer to apply to multiple fields in the index by default (e.g. to all text fields), consider using an [index template](https://www.elastic.co/guide/en/elasticsearch/reference/current/index-templates.html).
