SilverStripe FULLTEXT search function

Introduction

This behemoth handles extensive search and sorts on relevance.

##Features

Fulltextsearch enabled objects are stored in a separate table.
Searches ALL Fulltextsearch enabled objects.
Returns a DataObjectSet which can be easily handled.
Return is sorted by relevance, not just a list of results.
Reports for most used searches so you can optimize your website-design maybe.
Reports for searches in general.
Adds a default search keywords function to all pages for better searchresults.

Installation

Make a fork of this module.
In your site-root, do git clone https://{your username}@github.com/{your username}/silverstripe-searcher.git.
Add FulltextSearchable::enable(); to your _config in mysite.
Run in your browser - www.example.com/dev/build to rebuild the database.
You should see a new PageType in the CMS 'Search Results Page'.

Best practices

Use 'Content' as the default for a DataObject's main content. See known issues.
Use 'PublishFrom' and 'PublishUntil' as custom published-limits for the extra filter which is currently only applied to my own news-module.
The method 'SearchKeywords' is optional. The field adds a priority over actual content if it exists (and has data).

Configuration

Check if a page from the SiteTree should be shown in search under Behaviour-tab to have it show in search (defaults to true/checked)
The better the keywords, the more chance they end up high in search results. Choose wisely.
Any DataObject that should be searched should be set in the _config with DataObject::add_extension('ObjectName', 'FulltextSearchable('Title,Content,Extrafield,etc.'));.
When adding a FulltextSearchable, you need to run a dev/build for it to be recorded in the SearchObject and have the fulltext enabled in the database.

Future plans

Integrate a highlighter for searchresults.
Give a range-option for the results. So pages won't go waaaaay down.

Known issues:

It's assumed, the searchable classes have a Title to search. Can't be fixed since I can't look into your brain on what you are using as Title. Title is required, since it is keyworded, not just keymatched.

Requests

Please create a translation in your language if it doesn't exist yet!

Great thanks to DasPlan for finding and rudimentary implementing the query in the very first version we ever build.

The actual query

SELECT *,

CASE WHEN ClassName LIKE '%{searchquery}%' THEN 1 ELSE 0 END AS searchmatch,

CASE WHEN URLSegment LIKE '%{searchquery}%' THEN 1 ELSE 0 END AS searchmatch,

CASE WHEN Title LIKE '%{searchquery}%' THEN 1 ELSE 0 END AS titlematch,

CASE WHEN MenuTitle LIKE '%{searchquery}%' THEN 1 ELSE 0 END AS searchmatch,

CASE WHEN Content LIKE '%{searchquery}%' THEN 1 ELSE 0 END AS searchmatch,

CASE WHEN MetaTitle LIKE '%{searchquery}%' THEN 1 ELSE 0 END AS searchmatch,

CASE WHEN MetaDescription LIKE '%{searchquery}%' THEN 1 ELSE 0 END AS searchmatch,

CASE WHEN MetaKeywords LIKE '%{searchquery}%' THEN 1 ELSE 0 END AS searchmatch,

CASE WHEN ExtraMeta LIKE '%{searchquery}%' THEN 1 ELSE 0 END AS searchmatch,

CASE WHEN SearchKeywords LIKE '%{searchquery}%' THEN 1 ELSE 0 END AS keywordmatch,

MATCH (Title,MenuTitle,Content,MetaTitle,MetaDescription,MetaKeywords,SearchKeywords) AGAINST ('{searchquery}') AS relevance

FROM SiteTree

WHERE (ShowInSearch = 1) AND (Status = 'Published') AND (ClassName LIKE '%{searchquery}%' OR URLSegment LIKE '%{searchquery}%' OR Title LIKE '%{searchquery}%' OR MenuTitle LIKE '%{searchquery}%' OR Content LIKE '%{searchquery}%' OR MetaTitle LIKE '%{searchquery}%' OR MetaDescription LIKE '%{searchquery}%' OR MetaKeywords LIKE '%{searchquery}%' OR ExtraMeta LIKE '%{searchquery}%' OR SearchKeywords LIKE '%{searchquery}%' OR MATCH(Title,MenuTitle,Content,MetaTitle,MetaDescription,MetaKeywords,SearchKeywords) AGAINST ('{searchquery}' IN BOOLEAN MODE))

HAVING ( searchmatch > 0 OR keywordmatch > 0 OR titlematch > 0 OR relevance > 0 )

ORDER BY searchmatch DESC, keywordmatch DESC, titlematch DESC, relevance DESC
