我這裡用到的建立索引主要用來進行中文分詞搜尋和拼音搜尋功能，建立語句如下：
1、建立索引：
PUT /lzjsyd/ { "index" : { "analysis" : { "analyzer" : { "pinyin_analyzer" : { "tokenizer" : "rfpinyin", "filter" : "pinyin_first_letter_and_full_pinyin_filter" } }, "tokenizer" : { "rfpinyin" : { "type" : "pinyin", "keep_separate_first_letter" : true, "keep_full_pinyin" : true, "keep_original" : true, "limit_first_letter_length" : 16, "lowercase" : true, "remove_duplicated_term" : false } }, "filter" : { "pinyin_first_letter_and_full_pinyin_filter" : { "type" : "pinyin", "keep_first_letter" : true, "keep_full_pinyin" : false "keep_none_chinese" : true, "keep_original" : false, "limit_first_letter_length" : 16, "lowercase" : true, "trim_whitespace" : true, "keep_none_chinese_in_first_letter" : true } } } } }
2、設定：
PUT /lzjsyd/ { "index" : { "analysis" : { "analyzer" : { "pinyin_analyzer" : { "tokenizer" : "whitespace", "filter" : "pinyin_first_letter_and_full_pinyin_filter" } }, "filter" : { "pinyin_first_letter_and_full_pinyin_filter" : { "type" : "pinyin", "keep_first_letter" : true, "keep_full_pinyin" : false, "keep_none_chinese" : true, "keep_original" : false, "limit_first_letter_length" : 16, "lowercase" : true, "trim_whitespace" : true, "keep_none_chinese_in_first_letter" : true } } } } }
3、新增Mapping：
POST /lzjsyd/view_search/_mapping { "view_search": { "properties": { "cxmc": { "type":"text", "analyzer": "ik_max_word", "search_analyzer": "ik_max_word", "boost": 8, "fields": { "title":{ "type": "text", "analyzer": "ik_max_word" }, "pinyin": { "type": "text", "store": false, "term_vector": "with_offsets", "analyzer": "pinyin_analyzer", "boost": 1 } } } } } }
4、刪除查詢結果
POST lzjsyd/view_search/_delete_by_query
{
"query": {
"match_all": {}
}
}
