README
This plugin is a Search Plugin, to be used together with
Installation
Install via composer with your favorite adaptor:
ElasticSearch
composer require flowpack/searchplugin flowpack/elasticsearch-contentrepositoryadaptor
SimpleSearch
composer require flowpack/searchplugin flowpack/simplesearch-contentrepositoryadaptor
Inclusion of the routes from this package into your main Configuration/Routes.yaml
is no longer needed as of Flow 4.0.
Configuration
Custom index name
It is usually a good idea to specify a custom index name for a project, instead of the default typo3cr
. That
way no conflicts can arise when multiple projects use the same Elasticsearch server.
To specify a custom index name, the following is needed:
Neos:
ContentRepository:
Search:
elasticSearch:
indexName: acmecom
Pagination
The pagination search results can be configured via Fusion. The following shows the defaults:
prototype(Flowpack.SearchPlugin:Search).configuration {
itemsPerPage = 25
insertAbove = false
insertBelow = true
maximumNumberOfLinks = 10
}
Custom result rendering
The result list is rendered using a Fusion object of type nodeType + 'SearchResult'
for each hit.
Thus you can easily adjust the rendering per type like this for an imaginary Acme.AcmeCom:Product
nodetype:
prototype(Acme.AcmeCom:ProductSearchResult) < prototype(Neos.Neos:DocumentSearchResult) {
templatePath = 'resource://Acme.AcmeCom/Private/Templates/SearchResult/ProductSearchResult.html'
}
Feel free to use the DocumentSearchResult.html
in the Flowpack.SearchPlugin as an example.
Search completions and suggestions
The default search form template comes with a data-autocomplete-source
attribute pointing to the
SuggestController
of this package.
To use this term suggester, you need to configure the indexing like this, to define a custom analyzer to be used:
Flowpack:
ElasticSearch:
indexes:
default: # client name used to connect (see Flowpack.ElasticSearch.clients)
acmecom: # your (custom) index name
settings:
analysis:
filter:
autocompleteFilter:
max_shingle_size: 5
min_shingle_size: 2
type: 'shingle'
analyzer:
autocomplete:
filter: [ 'lowercase', 'autocompleteFilter' ]
char_filter: [ 'html_strip' ]
type: 'custom'
tokenizer: 'standard'
Then you need to configure the node types to be be included in the suggestion building, this can be done like this:
'Neos.Neos:Document':
superTypes:
'Flowpack.SearchPlugin:SuggestableMixin': true
'Flowpack.SearchPlugin:AutocompletableMixin': true
'Neos.Neos:Shortcut':
superTypes:
'Flowpack.SearchPlugin:SuggestableMixin': false
'Flowpack.SearchPlugin:AutocompletableMixin': false
'Neos.NodeTypes:TitleMixin':
superTypes:
'Flowpack.SearchPlugin:SuggestableMixin': true
'Flowpack.SearchPlugin:AutocompletableMixin': true
When fed with a term
parameter via a GET
request, the SuggestController
will return a
JSON-encoded array of suggestions from Elasticsearch. They are fetched with a term suggester
from the _all
field, i.e. "the fulltext index".
These can be used to provide autocompletion on the search input using a JS library of your choice. In case you need to build the URI to the suggest controller yourself, this is what the form uses:
{f:uri.action(action: 'index', controller: 'Suggest', package: 'Flowpack.SearchPlugin', format: 'json', absolute: 1, arguments: {contextNodeIdentifier: node.identifier, dimensionCombination: dimensionCombination})}
Adjust the suggestion context
The suggestionContext determines, if a result should be displayed in suggetions. By default, nodes that are hidden are excluded.
In many projects, the search als takes the Neos.Seo metaRobotsNoindex property into account or excludes certain nodeTypes. In order to adjust the suggestion context to your search logic, you can write your custom logic and switch the implementation of the Flowpack\SearchPlugin\Suggestion\SuggestionContextInterface
via Objects.yaml
Create URIs for suggestions
To create valid links for suggestions the following package can be used:
Connect the given example of this package with a custom fusion object:
pathToProtoType = Your.Vendor:Content.NodeLink
And finally add the new property to the plugin settings:
Flowpack:
SearchPlugin:
searchAsYouType:
suggestions:
sourceFields:
- title
- __myProperty
AJAX search
The plugin comes with a controller that can be reached like this per default, using GET
:
{f:uri.action(action: 'search', controller: 'AjaxSearch', package: 'Flowpack.SearchPlugin', arguments: {node: node, q: ''}, absolute: 1)}
It expects the search term as a parameter named q
(as defined in AjaxSearch.fusion
). This controller
renders the search results and returns them as HTML without any of the page template. It can therefore
be used to request search results via AJAX and display the result by adding it to the DOM as needed.
Removing special chars from search term
It is recommended to remove characters, which are reserved in Elasticsearch from the search term to prevent errors. There is an eel helper to replace them before submitting the search like this:
prototype(Flowpack.SearchPlugin:Search) {
searchTerm = ${Flowpack.SearchPlugin.SearchTerm.sanitize(request.arguments.search)}
}
Keep in mind, that this blocks the explicit use of wildcards (*
) and phrase search ("search exactly this"
)
for your users, in case you want to support that.
