Elasticsearch的Path Hierarchy
Tokenizer正是针对这种用例而创建的。这是如何为您的索引设置它的示例：
# Create a new index with custom path_hierarchy analyzer # See http://www.elasticsearch.org/guide/reference/index-modules/analysis/pathhierarchy-tokenizer.htmlcurl -XPUT "localhost:9200/prefix-test" -d '{ "settings": { "analysis": { "analyzer": { "prefix-test-analyzer": { "type": "custom", "tokenizer": "prefix-test-tokenizer" } }, "tokenizer": { "prefix-test-tokenizer": { "type": "path_hierarchy", "delimiter": "." } } } }, "mappings": { "doc": { "properties": { "dots": { "type": "string", "analyzer": "prefix-test-analyzer", //"index_analyzer": "prefix-test-analyzer", //deprecated "search_analyzer": "keyword" } } } }}'echo# Put some test datacurl -XPUT "localhost:9200/prefix-test/doc/1" -d '{"dots": "first.second.third"}'curl -XPUT "localhost:9200/prefix-test/doc/2" -d '{"dots": "first.second.foo-bar"}'curl -XPUT "localhost:9200/prefix-test/doc/3" -d '{"dots": "first.baz.something"}'curl -XPOST "localhost:9200/prefix-test/_refresh"echo# Test searches. curl -XPOST "localhost:9200/prefix-test/doc/_search?pretty=true" -d '{ "query": { "term": { "dots": "first" } }}'echocurl -XPOST "localhost:9200/prefix-test/doc/_search?pretty=true" -d '{ "query": { "term": { "dots": "first.second" } }}'echocurl -XPOST "localhost:9200/prefix-test/doc/_search?pretty=true" -d '{ "query": { "term": { "dots": "first.second.foo-bar" } }}'echocurl -XPOST "localhost:9200/prefix-test/doc/_search?pretty=true&q=dots:first.second"echo
