This module provides a simple but very flexible way to create a search index of almost any ActiveRecord entries.
The base idea is:
- we want a search index for every (configured) app language
- we want to group different Types of Models in search results
- we want to be able to get simple strings for different Types of Models where we can execute simple LIKE SQL queries on. No matter where the data for these strings come from.
- we want a fast frontend for the search module, so all required info to build links for the results should be pre-defined
see Module for available module params. These should allow to customize almost all aspects of the module and its behavior.
simple example config:
'modules' => [
'search' => [
'class' => \dmstr\activeRecordSearch\Module::class,
'layout' => '@backend/views/layouts/box',
'frontendLayout' => '@app/views/layouts/container',
],
]The module provides 2 types of controllers:
- frontend:
\dmstr\activeRecordSearch\controllers\FrontendController
- backend:
\dmstr\activeRecordSearch\controllers\SearchGroupControllerto manage (translate, en/disable) search groups which are created by the indexer\dmstr\activeRecordSearch\controllers\SearchControllerto manage search items, attentions these will be overwritten by next indexer run. Should usually not be required\dmstr\activeRecordSearch\controllers\SearchGroupTranslationControllersearch group translations. Should usually not be required
Additionally the module provide a simple Search-Input widget:
\dmstr\activeRecordSearch\widgets\SearchInputwhich will be used in frontend controller if not overwritten via modulsearchInputWidgetproperty
The heart of this module is the SearchIndexer.
The Indexer has to be configured for all Type of Models that should be indexed.
see SearchIndexer for available module params and example.
The Indexer should be defined and called as yii cli cmd:
$config['controllerMap']['search-index'] = \dmstr\activeRecordSearch\commands\IndexController::class;
To automate indexer runs create cron jobs.
Example script which can run as cron
#!/bin/bash
. /root/export-env
LOG=/tmp/search-index-update
date > $LOG
yii search-index/update >> $LOG
date >> $LOG
- In this example we index 2 types of models (products and accessories)
- For both types we define the AR model classes. These will be used to get the "data" by calling their
find()->all()Methods - The string that we will use for the search will be build (concatenation) from the values of the defined
attributes - For both types we definie the route that should be used to build the URL in results
- We also define which url_params should be used to build the result URL
link_textdefines the text for the result Link

- Here we define a bunch of different types where you can see that almost every param can be a callback so that one is able to define "non-static" results.
- The find_method param can be used to overwrite the default find(). Useful to filter models e.g. by their status flags
- Callbacks can be used in almost any place e.g. to generate link_text values from more than one attribute or even from attributes of different models (see tags where we use name prefixed by the name from tagGroup relation model)
products['attributes']is an example where you can see how to define virtual attributes from relation models with simple array notationnews['attributes']['content']is an example how to get parts of a json struct as 'content'- if you have SEO url rules, you can define all required
