Hi Alex,
First create your index with the synonym filter:
curl -XPUT 'localhost:9200/myindex/' -d '{
"settings": {
"index": {
"analysis": {
"filter": {
"synonym_filter": {
"type": "synonym",
"synonyms": [
"foo, foo bar => core"
]
}
},
"analyzer": {
"synonym": {
"tokenizer": "whitespace",
"filter": [
"synonym_filter"
],
"type": "custom"
}
}
}
}
}
}'
After index one document with the title equals do "core":
curl -XPOST 'localhost:9200/myindex/test/1' -d '{
"title": "core"
}'
Then search for "foo":
curl -XPOST localhost:1980/myindex/_search -d '{
"query": {
"multi_match": {
"query": "foo",
"fields": [
"title"
],
"type": "phrase_prefix",
"analyzer": "synonym"
}
}
}'
The response is the previous indexed document:
{
"took": 1,
"timed_out": false,
"_shards": {
"total": 1,
"successful": 1,
"failed": 0
},
"hits": {
"total": 1,
"max_score": 0.30685282,
"hits": [
{
"_index": "myindex",
"_type": "test",
"_id": "1",
"_score": 0.30685282,
"_source": {
"title": "core"
}
}
]
}
}

Hello Luiz, thank you for your reply!
As we use rivers, I was told to declare the analyzer there.
It looks like this for me:
{
"index" : {
"analysis" : {
"filter" : {
"synonym_filter" : {
"type" : "synonym",
"synonyms" : [
"foo, foo bar => core"
]
}
},
"analyzer" : {
"synonym" : {
"tokenizer" : "whitespace",
"filter" : [
"synonym_filter"
],
"type" : "custom",
}
}
}
}
}
which acctually says, for testing-purpose, 'if someone searches for 'foo'
or 'foo bar', search for 'core' '
Now my query uses the analyzer:
{
"query": {
"bool": {
"should": [
{
"multi_match": {
"query": "foo",
"fields": [
"TITLE",
"SHORTDESC"
],
"type": "phrase_prefix",
"analyzer": "synonym"
}
},
{
"multi_match": {
"query": "foo",
"cutoff_frequency": null,
"fields": [
"TITLE",
"SHORTDESC"
]
}
}
]
}
},
"filter": {
"term": {
"ACTIVE": 1
}
},
"sort": {
"TITLE": {
"order": "asc"
}
},
"size": 7
}
But I get an error there:
[...]nested: QueryParsingException[[test484] [multi_match] analyzer
[synonym] not found];[...]
What am I doing wrong here?

Hello there,
i have a query, example is this:
{
"query": {
"bool": {
"should": [
{
"multi_match": {
"query": "foo",
"fields": [
"TITLE",
"SHORTDESC"
],
"type": "phrase_prefix"
}
},
{
"multi_match": {
"query": "foo",
"cutoff_frequency": null,
"fields": [
"TITLE",
"SHORTDESC"
]
}
}
]
}
},
"filter": {
"term": {
"ACTIVE": 1
}
},
"sort": {
"TITLE": {
"order": "asc"
}
},
"size": 7
}
Now I have the question if I can use synonyms here?
I already saw that you can use a synonym-token inside an analyzer.
But I have a query here, not an analyzer.
Do I have to put an analyzer inside the query?
I don't know much about ES yet, so this may be a total stupid question.
Thank you in advance
