Usually, RiSearch PHP implements full-text search by converting the documents that need to be searched into a format suitable for searching and establishing indexes. This requires defining the fields of the document and the weight of the fields to facilitate sorting based on keywords.
3. Implementing the search function
   In the search function of the website, we need to interact with RiSearch PHP to implement the search function.

We can define the fields of the book, such as title, author, publisher, introduction, etc., and then convert these fields into the format supported by RiSearch and create indexes.

Next, we need to implement the search function on the search page of the website. First, we need to introduce the API provided by RiSearch PHP into the page. In the search box, use the form form to pass the keywords entered by the user to the background PHP script. In the PHP script, we first need to connect to the RiSearch search engine and set relevant parameters, such as index path, search method, etc. Then, by calling the search function provided by RiSearch, the keywords entered by the user are passed in and the search results are obtained. Finally, the search results are displayed on the website.
