OrientDB：如何在手动lucene索引中搜索指定的字段？

Question

我使用的是OrientDB 2.1.8社区和内置的Lucene索引。如何在手动索引中定义在搜索过程中要使用的字段？即。按照文档中使用多个字段页面中描述的方式使用手动索引？

下面是一个简短的例子来展示我正在努力做的事情。

CREATE VERTEX CONTENT {"name": "squirrel"}
  // rid = #9:2
CREATE VERTEX CONTENT {"name": "scrat", "description": "Scrat was an acorn-obsessed saber-toothed squirrel"}
  // rid = #9:3

CREATE INDEX manual FULLTEXT ENGINE LUCENE STRING,STRING
INSERT INTO INDEX:manual (key,rid) VALUES ('squirrel', #9:2)
INSERT INTO INDEX:manual (key,rid) VALUES (['scrat', 'scrat was an acorn-obsessed saber-toothed squirrel'], #9:3)

Answer 1

我已经尝试使用Create index manual FULLTEXT ENGINE LUCENE STRING,STRING METADATA{“analyzer”：“org.apache.LUCENE.analysis.core.KeywordAnalyzer”}并有效

CREATE VERTEX CONTENT {"name": "squirrel"}

CREATE VERTEX CONTENT {"name": "scrat", "description": "Scrat was an acorn-obsessed saber-toothed squirrel"}

create index manual FULLTEXT ENGINE LUCENE STRING,STRING METADATA {"analyzer":"org.apache.lucene.analysis.core.KeywordAnalyzer"} 

INSERT INTO INDEX:manual (key,rid) VALUES ('squirrel', #9:0)

INSERT INTO INDEX:manual (key,rid) VALUES (['scrat', 'scrat was an acorn-obsessed saber-toothed squirrel'], #9:1)
