查询索引的字段
get event_news/_mapping
模糊查询1
wildcard：
（好用）
get event_news/_search
{“from”:0,“size”:10,“query”:{“bool”:{“should”:[{“wildcard”:{“title_ch.keyword”:{“wildcard”:“1111”,“boost”:1}}}],“adjust_pure_negative”:true,“boost”:1}},“aggregations”:{“one”:{“terms”:{“field”:“media”,“size”:10,“min_doc_count”:1,“shard_min_doc_count”:0,“show_term_doc_count_error”:false,“order”:[{"_count":“desc”},{"_key":“asc”}]}}}}
fuzzy：
（需要再看）
get event_news/_search
{“from”:0,“size”:0,“query”:{“bool”:{“should”:[{“fuzzy”:{“title_ch.keyword”:{“value”:“啊啊啊”,“fuzziness”:“AUTO”,“prefix_length”:0,“max_expansions”:50,“transpositions”:true,“boost”:1.0}}}],“adjust_pure_negative”:true,“boost”:1.0}},“aggregations”:{“one”:{“terms”:{“field”:“media”,“size”:10,“min_doc_count”:1,“shard_min_doc_count”:0,“show_term_doc_count_error”:false,“order”:[{"_count":“desc”},{"_key":“asc”}]}}}}
match_phrase：
（好用）
get event_news/_search
{“from”:0,“size”:10,“query”:{“bool”:{“should”:[{“match_phrase”:{“title_ch”:{“query”:“aaa”,“slop”:0,“zero_terms_query”:“NONE”,“boost”:1.0}}}],“adjust_pure_negative”:true,“boost”:1.0}},“aggregations”:{“one”:{“terms”:{“field”:“media”,“size”:10,“min_doc_count”:1,“shard_min_doc_count”:0,“show_term_doc_count_error”:false,“order”:[{"_count":“desc”},{"_key":“asc”}]}}}}
match_phrase_prefix：匹配前缀
（没有匹配前缀，）
get event_news/_search
{“from”:0,“size”:100,“query”:{“bool”:{“should”:[{“match_phrase_prefix”:{“title_ch”:{“query”:“aaa苦”,“slop”:0,“max_expansions”:50,“zero_terms_query”:“NONE”,“boost”:1.0}}}],“adjust_pure_negative”:true,“boost”:1.0}},“aggregations”:{“one”:{“terms”:{“field”:“media”,“size”:10,“min_doc_count”:1,“shard_min_doc_count”:0,“show_term_doc_count_error”:false,“order”:[{"_count":“desc”},{"_key":“asc”}]}}}}
