FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.
Informations about the package elasticsearch
About
Elastic search was recently used to index the Firefox4 twitter stream and make it searchable. It's based on Lucene and has a simple JSON based interface that you can use to store objects and search through them (for instance even with CURL).
This also makes it easy to have your search indexes be updated in realtime whenever your CakePHP models change data. Cause basically all we'd have to do is do a Curl PUT, DELETE, etc to also make the change in Elastisearch with every afterSave and afterDelete.
This plugin provides
- a behavior to automatically update your indexes
- a shell task to do full index fills
- a generic search component that you can attach to your AppController and will intercept search actions on enabled models. Will return results in JSON format for easy AJAX integration.
Installation
You'll need the PHP curl libraries installed.

Integration
Database
Config/database.php
Model
Models/Ticket.php (minimal example)
Models/Ticket.php (with raw sql for huge datasets)
Models/Ticket.php (full example)
Controller
To automatically enable a /<controller>/searcher url on all models
that have elastic search enabled, use:
Controller/AppController.php
This component will only actually fire when the Controller->modelClass has the searchable behavior attached.
I chose for this method (vs a dedicated SearchesController) so ACLing is easier. e.g. You may already have an ACL for /tickets/*, so /tickets/search will automatically be restricted the same way.
Generic search
If you want to search on all models, you could make a dedicated search controller and instruct to search on everything like so:
One known limitation is that the Elasticsearch plugin will only look at the
first configured Model for configuration parameters like searcher_param
and searcher_action.

jQuery integration
Let's look at an integration example that uses jQuery UI's autocomplete.
Assuming you have included that library, and have an input field with attributes
id="main-search" and target="/tickets/searcher/q:*{query}*":
Note
- There also is an unmaintained legacy cakephp 1.3 branch
