Hello, it seems synonyms in 2nd file are not taken into account if already used in 1st file. In 1st file, I have: aaa,bbb In second file, I have: aaa,synaaa bbb,synbbb ccc,synccc When I do the \_analyze ```auto { "explain": false, "analyzer": "synonym_full_indexing_analyzer", "text" : "ccc" } ``` I get for: - aaa --\> aaa, bbb (I am not getting synaaa) - bbb --\> aaa, bbb (I am not getting synbbb) - ccc --\> ccc, synccc I wonder if it is related to that: > I didn't check the Elastic code. Here is the analyzer: ```auto "synonym_full_indexing_analyzer": { "type": "custom", "tokenizer": "fr_full_text_nospace_tokenizer", "filter": [ "conditional_elision", "lowercase", "asciifolding", "full_indexing_synonyms_syn1", "full_indexing_synonyms_syn2", "flatten_graph" ] }, ``` Elastic 7.17.6 ---

Hi @antoinelefloch I did this example based to [post](https://www.elastic.co/blog/boosting-the-power-of-elasticsearch-with-synonyms/). Chaining synonym filters seems to be possible. I'm not sure what your filters are other than synonyms and maybe they are the real problem. ```auto PUT /synonym_chaining { "settings": { "index": { "analysis": { "filter": { "first_synonyms": { "type": "synonym", "synonyms": ["aaa,bbb"] }, "second_synonyms": { "type": "synonym", "synonyms": ["aaa,synaaa","bbb,synbbb","ccc,synccc"] } }, "analyzer": { "synonym_analyzer": { "filter": [ "first_synonyms", "second_synonyms" ], "tokenizer": "whitespace" } } } } } } GET /synonym_chaining/_analyze { "analyzer": "synonym_analyzer", "text": "bbb" } ``` Tokens: ```auto { "tokens": [ { "token": "bbb", "start_offset": 0, "end_offset": 3, "type": "word", "position": 0 }, { "token": "synbbb", "start_offset": 0, "end_offset": 3, "type": "SYNONYM", "position": 0 }, { "token": "aaa", "start_offset": 0, "end_offset": 3, "type": "SYNONYM", "position": 0 }, { "token": "synaaa", "start_offset": 0, "end_offset": 3, "type": "SYNONYM", "position": 0 } ] } ``` ---

when I try to use simple settings, the second synonym file is not taken into account anymore. This is Elastic 7.7.1 ```auto PUT /synonym_chaining_files { "settings": { "index": { "analysis": { "filter": { "first_synonyms": { "type": "synonym", "synonyms_path": "resources/v1_02/my_synonyms_1.txt" }, "second_synonyms": { "type": "synonym", "synonyms": "resources/v1_02/my_synonyms_2.txt" } }, "analyzer": { "synonym_analyzer": { "filter": [ "first_synonyms", "second_synonyms" ], "tokenizer": "whitespace" } } } } } } ``` ---

> [@antoinelefloch](#): > > ```auto > "second_synonyms": { > "type": "synonym", > "synonyms": "resources/v1_02/my_synonyms_2.txt" > } > > ``` try replace **synonyms** to **synonyms\_path** ---

It works much better, thank you 🙂 I found the reason of my problem. It is related to my analyzer which has filters typed "synonym\_graph" and not simply "synonym". Here are the filters to reproduce the problem: ```auto "filter": { "first_synonyms": { "type": "synonym_graph", "synonyms": ["aaa,bbb"], "lenient": "true" }, "second_synonyms": { "type": "synonym_graph", "synonyms": ["aaa,synaaa","bbb,synbbb","ccc,synccc"], "lenient": "true" } } ``` If I remove "lenient", I get the error: "term: aaa analyzed to a token (aaa) with position increment != 1 (got: 0)" So I suppose synonym\_graph typed filters do not support having the same synonym token in 2 different synonym filters. ---
