Hi i m trying to use synonym file in ES 2.3.4. from the documentation i used the following command in SENSE: POST /mise/ { "index" : { "analysis" : { "analyzer" : { "synonym" : { "tokenizer" : "whitespace", "filter" : ["synonym"] } }, "filter" : { "synonym" : { "type" : "synonym", "synonyms\_path" : "sinonimi/synonym.txt" } } } } } I want all thje synonyms to be equivalent. Below my synonym.txt file format: "abate,priore,superiore", "abbacchiare,avvilire,deprimere", "abbacchiarsi,abbattersi,abbiosciarsi,accasciarsi,avvilirsi,deprimersi,disperarsi,scoraggiarsi,sgomentarsi", "abbacchiato,abbattuto,accasciato,afflitto,affranto,annientato,costernato,demoralizzato,depresso,in crisi,infelice,malinconico,mogio,prostrato,sconfortato,scoraggiato,scorato,sfiduciato,triste", "abbacchio,agnello" I get the following error message: { "error": { "root\_cause": [ { "type": "index\_creation\_exception", "reason": "failed to create index" } ], "type": "illegal\_argument\_exception", "reason": "failed to build synonyms", "caused\_by": { "type": "malformed\_input\_exception", "reason": "Input length = 1" } }, "status": 400 } Could you please help me out? Cannot get around this issue. Thanx valerio ---

Yes i did it! It seems the error is related to the synonim itself. I meas if use 2 words for a synonym it doesnt work. For example the synonym row: "abbattere,ammainare,peggiorare,tirare giu" the term "tirare giu" causes the error. IT wants just one token. Is that right? valerio ---

Try: ``` abbattere, ammainare, peggiorare, tirare giu ``` Or: ``` abbattere, ammainare, peggiorare, tirare giu => abbattere ``` ---

Hi David and thanx. I must correct myself. Acutally it's not the 2 tokens synonym to create the error but the diacritic. the original row was: abbattere, ammainare, peggiorare, tirare giù =\> this causes the malformed error because of the ù If ireplace ù with u' it works! abbattere, ammainare, peggiorare, tirare giu' =\> OK Therefore i think i'm going to replace all the diacritics Thanx valerio ---

I m wondering whether it is possible defining an ascii\_folding filter(to remove diacritics )for the synonyms filter? Thanx valerio ---

You can apply the asciifolding token filter before the synonym filter in the filter chain when you define an analyzer. So `tirare giù` will become `tirare giu` before reaching the synonym token filter. ---
