This article introduces the relevant knowledge of "what to do if the search results of the jspXCMS foreground are not consistent with the actual content". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

Foreground search is not queried from the database using sql, but is implemented using the Lucene full-text search engine. The database uses like for query, which requires full table scanning. When the amount of data is large, the performance is very poor. The performance of full-text search engine is several orders of magnitude faster than the like query of database. Full-text search uses participle search, such as "which restaurant has the best taste", will find articles related to "restaurant", "taste" and "best"; if you use a database search, you must exactly match the corresponding string.

Full-text indexing must first analyze and process the data to be searched and save it to a unique file. In Jspxcms, the full-text index file is stored in the / WEB-INF/fulltext folder. Sometimes there may be a mismatch between the data in the database and the data in the full-text index, such as importing and exporting the database, manually deleting the data in the database, or accidentally deleting the file in / WEB-INF/fulltext. This is a mismatch between the content searched from the full-text index and the content of the database. At this time, you only need to go to the content management of the system backend-generate management, and click to generate full-text index. If there is a mismatch in the foreground search after the index is generated, you can delete all the contents in the / WEB-INF/fulltext folder and then go to the background to regenerate the full-text index.

This is the end of the content of "what if the search results of the jspXCMS receptionist are not consistent with the actual amount of content". Thank you for reading.
