Synonym search is failing with default FESS boolean operator "AND"

Hi ,

I have a problem with synonym search . When i search for “uninstall AND mms” , synonyms for uninstall and mms are not part of search query . But the same synonyms search is working when we search for “uninstall OR mms”

Is there a way to acheive results for both synonym and boolean query together . This default boolean operator AND is being used in FESS internally hence synonym search is not working .

Below is the configuration which we used in our FESS system.
“standard_search_analyzer”: {
“filter”: [
“disable_graph”,
“alphanum_word_filter”,
“cjk_bigram”,
“lowercase”,
“asciifolding”,
“stopword_en_filter”,
“english_keywords”,
“english_override”,
“stemmer_en_filter”,
“synonym_filter”
],
“char_filter”: [
“mapping_filter”
],
“type”: “custom”,
“tokenizer”: “standard”
},

	"standard_analyzer": {
      "filter": [
        "disable_graph",
        "alphanum_word_filter",
        "cjk_bigram",
        "lowercase",
        "asciifolding",
        "stopword_en_filter",
        "english_keywords",
        "english_override",
        "stemmer_en_filter",
        "synonym"
      ],
      "char_filter": [
        "mapping_filter"
      ],
      "type": "custom",
      "tokenizer": "standard"
    },

Please suggest us the solution.
