Elasticsearch之matchPhraseQuery如何正常解析特殊字符

我有一个索引数据，格式如下：

{

  "var_pmid" : {

    "aliases" : { },

    "mappings" : {

      "var_pmid_list" : {

        "properties" : {

          "cdna" : {

            "type" : "string"

          },

          "chr_id" : {

            "type" : "string"

          },

          "clinvarID" : {

            "type" : "string"

          },

          "gene" : {

            "type" : "string"

          },

          "mutation_id" : {

            "type" : "string"

          },

          "paper" : {

            "type" : "string"

          },

          "pmid" : {

            "type" : "string"

          },

          "resource" : {

            "type" : "string"

          },

          "snp" : {

            "type" : "string"

          },

          "snpeff_ann" : {

            "type" : "string"

          },

          "var" : {

            "type" : "string"

          },

          "var_s" : {

            "type" : "string"

          }

        }

      }

    },

    "settings" : {

      "index" : {

        "creation_date" : "1536392419200",

        "number_of_shards" : "5",

        "number_of_replicas" : "1",

        "uuid" : "DKmAfA1oTjSjnF7ZH8qDzA",

        "version" : {

          "created" : "2040699"

        }

      }

    },

    "warmers" : { }

  }

}

其中的 snpeff_ann的value有   "snpeff_ann" : "c.2326-49876C>T,c.1472A>G,n.1383-49876C>T,c.3445-49876C>T,n.4417-49876C>T" 这种。我需要用c.1472A>G去部分匹配。所以我用了spring-data-elasticsearch的QueryBuilders.matchPhraseQuery去匹配。但是可能是由于‘.>’等特殊字符的原因，返回的结果有不正确的。这种如何去处理呢？我的匹配代码如下：

BoolQueryBuilder boolQueryBuilder = QueryBuilders.boolQuery();

		boolQueryBuilder

			.should(QueryBuilders.matchPhraseQuery("paper", var))

			.should(QueryBuilders.matchPhraseQuery("snpeff_ann", var))

			.should(QueryBuilders.matchPhraseQuery("chr_id", var))

			.should(QueryBuilders.matchPhraseQuery("snp", var))

			.should(QueryBuilders.matchPhraseQuery("var_s", var))

			.should(QueryBuilders.matchPhraseQuery("var", var))

			.should(QueryBuilders.matchPhraseQuery("mutation_id", var))

			.should(QueryBuilders.matchPhraseQuery("cdna", var))

			.should(QueryBuilders.matchPhraseQuery("clinvarID", var));

		

		SearchQuery searchQuery2 = new NativeSearchQueryBuilder()

				.withQuery(boolQueryBuilder)

				.withIndices("var_pmid")

				.withTypes("var_pmid_list")

				.build();
