MySQL has support for full-text indexing and searching: A full-text index in MySQL is an index of type FULLTEXT . Full-text indexes can be used only with InnoDB or MyISAM tables, and can be created only for CHAR , VARCHAR , or TEXT columns.
https://dev.mysql.com/doc/refman/5.6/en/innodb-fulltext-index.html
InnoDB FULLTEXT indexes have an inverted index design. Inverted indexes store a list of words, and for each word, a list of documents that the word appears in. To support proximity search, position information for each word is also stored, as a byte offset.

This is the placeholder worklog for the ongoing development of the Full Text Search (FTS) project in InnoDB. The purpose of the Project is to provide user the ability to build Full Text Index on Text Document stored in the InnoDB storage engine, and provide them fast and accurate search on the Document Content.

Dec 21, 2012 · A few months ago, in MySQL 5.6.4, I took a brief look at MySQL 5.6’s new InnoDB Fulltext support; see Initial impressions of InnoDB Fulltext.There have been quite a few new point releases since then, and we’re into RC releases of MySQL 5.6 now, so I thought I’d take another look.

This is the place holder for CJK (Chinese, Japanese and Korea) support for InnoDB FULLTEXT search. 1) N-GRAM support The problem with CJK language is that each word could come from multiple characters. There is no fixed separators for individual words. So the idea is to index contiguous groups of N characters, or n-grams, instead.

The inverted index is partitioned into six auxiliary index tables to support parallel index creation. By default, two threads tokenize, sort, and insert words and associated data into the index tables. The number of threads is configurable using the innodb_ft_sort_pll_degree option.

Full-text searches are supported for MyISAM tables only. (In MySQL 5.6 and up, they can also be used with InnoDB tables.) Full-text searches are not supported for partitioned tables. See Section 19.5, “Restrictions and Limitations on Partitioning”.

A full-text index in MySQL is an index of type FULLTEXT. Full-text indexes can be used only with InnoDB or MyISAM tables, and can be created only for CHAR, VARCHAR, or TEXT columns. A FULLTEXT index definition can be given in the CREATE TABLE statement when a table is created, or added later using ALTER TABLE or CREATE INDEX.

This is part 3 of a 3 part series covering the new InnoDB full-text search features in MySQL 5.6. To catch up on the previous parts, see part 1 or part 2. Some of you may recall a few months ago that I promised a third part in my InnoDB full-text search (FTS) series, in which I’d actually take a look at the performance of InnoDB FTS in MySQL 5.6 versus traditional MyISAM FTS.

Problem Statement: ----- Support fulltext plugin parser to do tokenization and query parsing in InnoDB. Let's understand current implementation in InnoDB: - Use 'innobase_mysql_fts_get_token' to tokenize document directly. - Use bison/flex to parse query. - No interface or framework for fullext plugin parser.

InnoDB is a general-purpose storage engine that balances high reliability and high performance. In MySQL 8.0, InnoDB is the default MySQL storage engine. Unless you have configured a different default storage engine, issuing a CREATE TABLE statement without an ENGINE= clause creates an InnoDB table.. Key Advantages of InnoDB
