django怎么读（Django and fulltext search）

Lately I’ve been searching for a simple solution for full-text Model search using Django. Every task up to this point just seemed so easy, so I was a bit surprised to discover there’s no quick, clean and preferred way to go about adding site search functionality in the framework.

So far, the information I read seems to suggest existing solutions are:

Based on a dedicated full-text search module djangosearch Supposed to become the official search contrib. Rather recent history (during 2008). It’s an framework over existing, dedicated full text indexing engines: Lucene (Java version) Solr (still Java, and also based on Lucene) Xapian (C++) HyperEstraier django-sphinx Wrapper around Sphinx full-text search engine Based on a database engine full-text capability (ie. you must create full text indexes with appropriate DB commands) For the MySQL backend, there’s already a “fieldname__search
  
  
  
  
  
  
 ” syntax already supported in the framework, translating into a MATCH AGAINST query in SQL. Supports basic boolean operators Reference (look at the conclusion of the article) For PostgreSQL, depending on the version of the engine, there are solutions, but they seem complex, relative to the MySQL approach Most simple, but very inefficient: based on a simple LIKE %keyword% query Uses the “fieldname__icontains  
  
  
  
  
  
 ” filter syntax That’s what I used temporarily for get the feature going in my prototype

Other approaches are mentioned in this thread on StackOverflow.
