Postgres has built-in Full Text Search which we can use instead of cobbling together our own with like.Luckily for us, the Postgres FTS documentation is quite extensive, containing lots of information on the all-important Postgres search data types: tsvector and tsquery....
A document is the unit of searching in a full-text search system; for example, a magazine article or email message. --Postgres documentation document能够跨越多个表,它代表的是一个逻辑上的独立个体。 建立我们的document 在上一节我们介绍了document的概念,document和我们的表结构没关系,它只和数据有关系...
I removed the postgres-fulltext-search feature and used the backend-postgres on the new module. But we need to think about the optional arguments of built-in functions, can we simply have the optional arguments wrapped in Option? I already did it that way on the helper methods for the reg...

By default, Postgres uses'english'as text search configuration for the functionto_tsvectorand it will also ignore english stopwords. That explains why thetsvectorresults have fewer elements than the ones in our sentence. We see later a bit more about languages and text search configuration. ...
