Question for tokenizer and synonym

Elastic Stack Elasticsearch
1

I am having requirement similar to below:

  • search for "chevy" should map to search for "chevrolet". I am using
    synonyms to accomplish this.
  • search for "BMW 6 series" should map to "61i", "62i", "63i" and so on.
    I am planning to use synonyms to accomplish this too.

Field that contains either (chevrolet or 61i or 62i or 63i) is having
index analyzer as:

"synonym_analyzer" : {
"type": "custom",
"tokenizer": "standard",
"filter": [ "lowercase", "synonym_filter" ]
}

My issue with above standard tokenizer is that I cannot map "BMW 6 series" to "61i", "62i", "63i". I cannot use "keyword" tokenizer as the search could be: "chevy red" or "BMW 6 series v8".
I am open to changing tokenizers and other elements if required. Please advise.

Thanks,
Prateek

Hi,

I guess you are using query string query. If you use match query instead, it should work.
