hi

how i can combine a prefix query and a synonyme filter ?

this is my query :

{  
"query": {  
"query\_string": {  
"query": "samsung",  
"analyzer": "synonym",  
"fields": [  
"name\_fr.name\_fr",  
"name\_fr.whitespace",  
"name\_fr.edge\_ngram\_front",  
"name\_fr.edge\_ngram\_back",  
"name\_fr.shingle",  
"name\_fr.shingle\_strip\_ws",  
"name\_fr.shingle\_strip\_apos\_and\_ws",  
"name\_fr.analyzer\_fr",  
"manufacturer",  
"description\_fr.description\_fr",  
"description\_fr.synonym",  
"description\_fr.whitespace",  
"description\_fr.edge\_ngram\_front",  
"description\_fr.edge\_ngram\_back",  
"description\_fr.shingle",  
"description\_fr.shingle\_strip\_ws",  
"description\_fr.shingle\_strip\_apos\_and\_ws",  
"description\_fr.analyzer\_fr",  
]  
}  
},  
"min\_score": 0.2,  
"size": 8,  
"filter": {  
"synonym": {  
"type": "synonym"  
},  
"and": [  
{  
"prefix": {  
"name\_fr.shingle\_strip\_ws": "samsung"  
}  
},  
{  
"query": {  
"query\_string": {  
"query": "_exists_:type\_products\_fr"  
}  
}  
}  
]  
}  
}

but I have an exception

nested: QueryParsingException[[magento] No filter registered for [synonym]];

thank you

Hey,

The exception you are getting, is actually telling the truth a bit, however  
it is pretty hard to extract useful information out of it.

You are trying to use the synonym feature on query time, but this is not  
possible. The synonym feature is a tokenfilter and has to be configured,  
before you start indexing your documents. It is not to be used on query  
time at all.

Consider this example:

curl -X DELETE 'localhost:9200/mytest'  
curl -XPUT 'localhost:9200/mytest' -d '{  
"settings" : {  
"analysis" : {  
"analyzer" : {  
"my\_analyzer" : {  
"tokenizer" : "standard",  
"filter" : ["lowercase", "your\_synonym\_filter"]  
}  
},  
"filter" : {  
"your\_synonym\_filter" : {  
"type" : "synonym",  
"synonyms" : [  
"foo, bar"  
]  
}  
}  
}  
}  
}'

curl -X PUT localhost:9200/mytest/sometype/\_mapping -d ' { "sometype" : {  
"properties" : { "name" : { "type" : "string", "analyzer":"my\_analyzer"} }  
} }'

curl -X PUT localhost:9200/mytest/sometype/1 -d '{ "name" : "what a  
wonderful bar" }'

curl -X POST localhost:9200/mytest/sometype/\_search -d '{ "query" : {  
"match" : { "name" : "bar" } } }'  
curl -X POST localhost:9200/mytest/sometype/\_search -d '{ "query" : {  
"match" : { "name" : "foo" } } }'

When configuring the synonym filter in your index configuration, you can  
search either for foo or bar and the indexed document will be returned in  
both queries.

Hope this helps...

this query works fine 🙂

{  
"query": {  
"query\_string": {  
"query": "nabili",  
"analyzer": "synonym",  
"fields": [  
"name\_fr.name\_fr",

"description\_fr.synonym",  
"description\_fr.whitespace",  
"description\_fr.edge\_ngram\_front",  
"description\_fr.edge\_ngram\_back",  
"description\_fr.shingle",  
"description\_fr.shingle\_strip\_ws",  
"description\_fr.shingle\_strip\_apos\_and\_ws",  
"description\_fr.analyzer\_fr",  
"isbn\_fr",  
"manufacturer\_facet",  
"article\_code\_manufacturer",  
"ean",  
"book\_author"  
]  
}  
},  
"min\_score": 0.2,  
"size": 8,  
"filter": {  
"and": [  
{  
"query": {  
"query\_string": {  
"query": "_exists_:type\_products\_fr"  
}  
}  
}  
]  
}  
}

so the problem is with the prefix filter ☹
