My index setting -

{  
"settings": {  
"number\_of\_shards": 1,  
"analysis": {  
"filter": {  
"autocomplete\_filter": {  
"type": "edge\_ngram",  
"min\_gram": 1,  
"max\_gram": 50  
},  
"synonym" : {  
"type" : "synonym",  
"synonyms\_path" : "synonym.txt"  
}  
},  
"analyzer": {  
"autocomplete": {  
"type": "custom",  
"tokenizer": "standard",  
"filter": [  
"lowercase",  
"synonym",  
"autocomplete\_filter"  
]  
},  
"search\_synonyms" : {  
"tokenizer" : "standard",  
"filter" : ["synonym"]  
}  
}  
}  
}  
}

Indexing work well but at the time of search If I use autocomplete analyzer it produces synonym results but along with random match

Can you explain a bit more and show an example that illustrates your issue? You should also provide your mapping and what you're trying to search? There's probably a logical explanation behind this.

As explained in -[https://www.elastic.co/guide/en/elasticsearch/guide/master/\_index\_time\_search\_as\_you\_type.html](https://www.elastic.co/guide/en/elasticsearch/guide/master/_index_time_search_as_you_type.html)

I have created an index with edge-ngram and synonym filter.  
To support synonym at search time I have defined search\_synonyms analyzer.  
query time synonym also work with autocomplete analyzer but it produces a lot verbose result before an exact match  
and defined query time analyser won't work while search\_as\_you\_type it only work with exact match.
