Full-Text Search

Description

Replaces site search with full-text search.

Replace the site search from LIKE search to Japanese full-text search (MySQL + Ngram parser or Mroonga engine + TokenMecab parser). This will significantly improve search performance.

Search for pure strings (plain text) without HTML tags. This will prevent HTML tags from being searched.

The data (index) for searching is stored in a dedicated table. It does not rewrite existing table structures or post data (posts table).

Searches for text in PDF, Word (doc, docx), Excel, and PowerPoint files. Secured PDF file are currently not supported.

It supports WordPress multisite.

Search string options

  • OR (uppercase letter) – Combine searches. Example: foo OR bar
  • - – Exclude words from the search. Example: foo -bar
  • "" – Search for an exact match. Example: “foo bar”
  • * – Search by wildcard. Mroonga only. Example: foo*
  • () – Grouping. Mroonga only. Example: (foo OR bar) baz

Operating environment

Requires MySQL 5.6 or later, or Mroonga engine.

Mroonga engine is strongly recommended. InnoDB engine performs significantly worse with large amounts of data.

When I asked a question about using it with the WP Download Manager plugin, there was a polite answer about how to customize it, and it worked as desired. That’s excellent.

I am a user from China, and I have used the search plug-in developed by you; my website has 2 million pieces of data, and the plug-in developed by you can really run efficiently. But there is one question that I would like to give feedback, and at the same time I would like to ask you if there is a better way to deal with this situation. When searching for a keyword with a number such as \\\\\\\\\\\\\\\”10个\\\\\\\\\\\\\\\”, the plug-in does not return the result, but always displays the loading process, which may even cause the website to be abnormal. Hope to get your reply, thank you!
