I have a below mapping document, which to be precise does apply word delimiter analyzer at index and search time specifically only to model field and synonym analyzer which does a search time analysis on search string. Mapping ``` POST /stackoverflow { "settings":{ "analysis":{ "analyzer":{ "keyword_analyzer":{ "tokenizer":"keyword", "filter":[ "lowercase", "asciifolding" ] }, "synonym_analyzer":{ "tokenizer":"standard", "filter":[ "lowercase", "synonym" ], "expand":false, "ignore_case":true }, "word_delimiter_analyzer":{ "tokenizer":"whitespace", "filter":[ "lowercase", "word_delimiter" ], "ignore_case":true } }, "filter":{ "synonym":{ "type":"synonym", "synonyms_path":"synonyms.txt" }, "word_delimiter":{ "type":"word_delimiter", "generate_word_parts":true, "preserve_original": true } } } }, "mappings":{ "vehicles":{ "dynamic":"false", "dynamic_templates":[ { "no_index_template":{ "match":"*", "mapping":{ "index":"no", "include_in_all":false } } } ], "_all":{ "enabled":false }, "properties":{ "id":{ "type":"long", "ignore_malformed":true }, "model":{ "type":"nested", "include_in_root":true, "properties":{ "label":{ "type":"string", "analyzer": "word_delimiter_analyzer" } } }, "make":{ "type":"String", "analyzer":"keyword_analyzer" } } } } } ``` and some sample data is ``` POST /stackoverflow/vehicles/6 { "make" : "chevrolet", "model" : { "label" : "Silverado 2500HD" } } ``` The below is the search query ``` GET /stackoverflow/_search?explain { "from":0, "size":10, "query":{ "filtered":{ "query":{ "multi_match":{ "query":"HD2500", "fields":[ "make","model.label" ], "type":"cross_fields","operator" : "OR", "analyzer" : "synonym_analyzer" } } } } } ``` THe above search query does not work, rather if i remove the synonym\_analzer from the search query it works perfectly fine. I really dont understand the logic behind how synonym analyzer is tampering the result. In my synonym.txt file i dont have any reference to HD2500, and all the synonym analyzer does is split the token via whitespace and converts it to lowercase and then try to match a synonym string and then passes it to field level analyzers, i am confused where it is getting broken. Any help is highly appreciated ---

Any idea on this mystery? ---

I figured out, it cannot be done in elastic search. As soon as Synonym analyzer(query level) is applied on search string no other field level analyzer(word delimiter) will be applied ---

Not sure I fully follow your conclusion but if you want a search-time analyzer that includes both synonym and word-delimiter behaviour this could be defined in your mappings as ``` "search_time_synonym_and_worddelim_analyzer":{ "tokenizer":"standard", "filter":[ "lowercase", "synonym", "word_delimiter" ], "expand":false, "ignore_case":true }, ``` And running this search: ``` GET /test/vehicles/_search?explain { "from":0, "size":10, "query":{ "filtered":{ "query":{ "multi_match":{ "query":"HD2500", "fields":[ "make","model.label" ], "type":"cross_fields","operator" : "OR", "analyzer" : "search_time_synonym_and_worddelim_analyzer" } } } } } ``` I get a match ---

In the proposed solution scenario the word delimiter will be applied to all fields, rather i want word delimiter to be applied only to model field. In my case i want synonym analyzer to be applied to all fields and on top of that i want word delimiter to be specifically applied to model field alone. Conclusion : Either have analyzer on all the requiring fields or have a query level analyzer which gets applied to all fields. ---
