Phrase Match Query Problem

Elastic Stack Elasticsearch
1

Hi Guys,

For some reason when I do the following Phrase Match query I do not get any
results does anyone mind explaining why this is happening?

Below one can find the mapping and query being used

"settings": {

 "analysis": {

     "filter": {

             "token_ngrams": {

             "min_shingle_size": 2,

                 "max_shingle_size": 4,

                 "type": "shingle"

         },

             "synoynm_filter": {

             "synonyms_path": ".. path ...",

                 "type": "synonym"

         }

     },

     "analyzer": {

         "title_analyzer": {

             "filter": ["standard", "lowercase", "asciifolding",

"synoynm_filter", "porter_stem", "token_ngrams"],

                 "type": "custom",

                 "tokenizer": "standard"

         }

     }

 }

}

"match": {

 "_all": {

     "query": "CompassMD is a SaaS platform",

         "type": "phrase",

             "analyzer": "title_analyzer"

 }

}

So I did some more digging into the problem and apparently the problem is
not with the Phase Query but with the Analyser being user on the _all
field. When an Analyser is specified no results are returned but when I
omit the Analyser I get the expected results.

So the question is what is exactly happening internally on the _all field
is it using the standard analyser? is it not analysed?
