Hi everyone,

I am relatively new to elasticsearch and am having issues with getting my  
synonym filter to work. Can you take a look at the settings and tell me  
where I am going wrong?

I am expecting the search for "aids" to match the search results if I were  
to search for "retrovirology", but this is not happening.

Thanks!

Your issue is casing. You are only applying the synonym filter, which by  
default does not lowercase terms. You can either set ignore\_case to true  
for the synonym filter or apply a lower case filter before the synonym. I  
prefer to use the latter approach since I prefer to have all my analyzed  
tokens lowercased.

Also, you should only apply the synonym filter at index time. You would  
need to create two similar analyzers, one with the synonym filter and one  
without. You can set the different ones via index\_analyzer and  
search\_analyzer.

Thank you! That solved the initial issue.

Could you expand on why I would need two analyzers? I did what you asked,  
but I am unsure of the reason behind it and would like to learn.

Here are my updated settings:

curl -XPUT "[http://localhost:9200/personsearch](http://localhost:9200/personsearch)" -d'  
{  
"settings": {  
"index": {  
"analysis": {  
"analyzer": {  
"XYZSynAnalyzer": {  
"tokenizer": "whitespace",  
"filter": [  
"lowercase",  
"XYZSynFilter"  
]  
},  
"MyAnalyzer": {  
"tokenizer": "standard",  
"filter": [  
"standard",  
"lowercase",  
"stop"  
]  
}  
},  
"filter": {  
"XYZSynFilter": {  
"type": "synonym",  
"synonyms": [  
"aids, retrovirology"  
]  
}  
}  
}  
}  
},  
"mappings": {  
"xyzemployee": {  
"\_all": {  
"analyzer": "XYZSynAnalyzer"  
},  
"properties": {  
"firstName": {  
"type": "string"  
},  
"lastName": {  
"type": "string"  
},  
"middleName": {  
"type": "string",  
"include\_in\_all": false,  
"index": "not\_analyzed"  
},  
"specialty": {  
"type": "string",  
"index\_analyzer": "XYZSynAnalyzer",  
"search\_analyzer": "MyAnalyzer"  
}  
}  
}  
}  
}'

A couple of reasons. The biggest issue is multi word synonyms since the  
query parser will tokenize the query before analysis is applied. Also,  
scoring could be affected and the results can be screwy. Here is a better  
write up:

I appreciate the fact that you want to know why you shouldn't use synonyms  
at query time. I couldn't find the following articles during my last  
response (I read them a while back and I have waaaaay too many bookmarks),  
but I finally found them:

Ivan, thank you feeding my curiosity! The first one really gave me an
