在Neo4j中跨多个字段进行全文搜索的示例? [英] Example of full-text search across multiple fields in Neo4j?

问题描述

我看过一些简单的示例文本搜索STARTS WITH name，例如:

I've seen some simple examples text searching STARTS WITH name such as:

• http://www.jexp.de/blog/html/full-text-and-spatial-search-in-neo4j-3.html
• https://blog. knoldus.com/2016/12/11/neo4j-with-scala-neo4j-vs-elasticsearch/

• https://blog.knoldus.com/2016/12/11/neo4j-with-scala-neo4j-vs-elasticsearch/

但是我正在寻找跨多个字段的全文搜索的更多内容:title，content:

But I'm looking for something more along the lines of full-text search across multiple fields: title, content:

• 我可以看到一个有关Neo4j如何完成此操作的示例吗?

  Can I see an example of how this should be done with Neo4j?

  推荐答案

  您可以使用

  You can do this using the APOC Neo4j procedure library. Let's say you have node labels Book and Author and you want to make a full text query across :Book(title), :Book(content), and :Author(name) and :Author(address). First, use apoc.index.addAllNodes to create an index called bookIndex and specify the labels and properties to include in the index:

  CALL apoc.index.addAllNodes('bookIndex',{
    Book: ["title","content"],
    Author:  ["name","address"]
  })
  

  然后，搜索索引:

  CALL apoc.index.search('bookIndex', 'River Runs Through It')
  

  您也可以将其用于更复杂的图形查询:

  You can use this with more complex graph queries as well:

  CALL apoc.index.search('bookIndex, 'River Runs Through It')
  YIELD node AS book
  MATCH (book)-[:IN_GENRE]->(g:Genre)
  RETURN g
  

  Lucene查询语法，因此您可以进行模糊搜索，这是必需的组件的字符串，等等:'Norman Maclean~'或'Norman~ +Maclean'

  Lucene query syntax is used so you can do fuzzy search, required components of the string, etc: 'Norman Maclean~' or 'Norman~ +Maclean'

  有关更多信息，请参见 APOC文档.
