Timo Hund gives an overview of using FLUID templating for search results in EXT:solr. He explains how search requests are processed, how the search result set is used to access results and facets, and how templates and partials can be customized. Facets can be configured as options, hierarchies, query groups, date ranges or numeric ranges. Custom templates and partials allow overriding the default rendering.

7. Searchbox

• Renders the search form only
• Can be used as entry point from outside to start a search
• Triggers SearchController::formAction

8. Searchbox

9. Frequent searches

• Renders frequent searches from the statistics
• Triggers SearchController::frequentlySearchedAction()

10. Frequent searches

13. Concepts & Structure
Concepts & Structure of the FLUID templating in EXT:solr
13(c) by Timo Hund & dkd Internet Service GmbH (Copy for internal use only).

14. Marker based templating
• Default before EXT:solr 7.0.0
(FLUID was not available when EXT:solr was started)
• Extended marker concept of the core (loops, if/else, …), innovative at
that time…
• Limitations
• No Partials
• Limited ViewHelpers
• Additional learning
• Implicite loading of JS and CSS files
• Spreathed logic for url generation
• Templateengine was part of the extension => more maintenance
• PI based (No MVC)
14

15. FLUID based templating
• Since 7.0.0 part of EXT:solr
• Brings
• Domain model for Results/Facets/Sorting/…
• Extbase controllers (MVC & DDD Pattern)
• Default fluid layouts/partials and templates
• ViewHelpers needed for search
• Unified url generation
• Performance improvements

EXT:solr builds this query
for your and queries the
Apache Solr Server

22. Example query and response
22
Apache Solr delivers a json/xml
response that contains facets, results …
EXT:solr creates the SearchResultSet from
that.
The SearchResultSet can be used to access
all needed data for the output

23. Search resultlist

FormSorting
Facet Area Results
Last Searches
Frequent Searches

24. Get domain objects from SearchResultSet

25. 25
Example:
<f:for each="{resultSet.searchResults}" as="result">
<h1>{result.title}</h1>
</f:for>
Get domain objects from SearchResultSet

26. Example:
<f:for each="{resultSet.facets.available}" as="facet">
<h1>{facet.label}</h1>
<f:for each="{facet.options}" as=“option“>
{option.label}
</f:for>
</f:for>
26
options, hierarchy, queryGroup
numericRange & dateRange
Get domain objects from SearchResultSet

27. Get domain objects from SearchResultSet
27
Example:
<f:if condition="{resultSet.sortings.hasSelected}">
<p>{resultSet.sortings.selected.label}</p>
</f:if>

28. Get domain objects from SearchResultSet

Example:
<p>{resultSet.usedSearchRequest.page}</p>

<f:if condition="{hasSearched}">
<f:if condition="{resultSet.usedSearch.numberOfResults}">
<f:render partial="Result/PerPage" section="PerPage" arguments="{resultSet: resultSet}" />

<f:render partial="Result/Document" section="Document"
arguments="{resultSet:resultSet, document:document}" />
</f:for>
</ol>
</s:widget.resultPaginate>
</f:if>
33
Every document is passed
to the Results/Document
partial to render the
search result
• You can use: EXT:solr/Resources/Private/Partials/Result/Document.html and
adapt it to your needs.

34. Faceting
What are facets and how to configure them?
34

35. Faceting
35
Facet Area

36. Faceting
• Facets help the user to „narrow down“ or „filter“ the results, to find
what he is looking for.
• Based on a solr field
• Configured with TypoScript
• Have different types
• Option
• Query Group
• Hierarchical
• Date Range
• Numeric Range
36

37. Example
Content type facet of a page:
plugin.tx_solr.search.faceting.facets {
type {
label = Content Type
field = type
type = options*
}
}
*type „options“ is default
37

38. Available option based facets
38
options
hierarchy
queryGroup
Flat list of selectable options
Nested tree of options
Flat list based on solr querys
Example: EXT:solr/Configuration/TypoScript/Examples/Facets/QueryGroup/setup.txt
Example: EXT:solr/Configuration/TypoScript/Examples/Facets/Hierarchy/setup.txt
Default Partial: EXT:solr/Resources/Private/Partials/Facets/Options.html
Default Partial: EXT:solr/Resources/Private/Partials/Facets/Hierarchy.html
Default Partial: EXT:solr/Resources/Private/Partials/Facets/Options.html

39. Available range based facets
39
numericRange
dateRange
Numeric range between a
min and max value
Date range between a start and
end date
Example: EXT:solr/Configuration/TypoScript/Examples/Facets/NumericRange/setup.txt
Example: EXT:solr/Configuration/TypoScript/Examples/Facets/DateRange/setup.txt
Default Partial: EXT:solr/Resources/Private/Partials/Facets/NumericRange.html
Default Partial: EXT:solr/Resources/Private/Partials/Facets/DateRange.html

40. Customizing
Use custom Templates / Partials or ViewHelpers
40

41. Resources
• EXT:solrfluidexample - example extension that shows how to use:
• Custom Templates
• Custom Translations
• Custom ViewHelpers
• https://github.com/TYPO3-Solr/ext-solrfluidexample
• EXT:solr documentation:
• https://docs.typo3.org/typo3cms/extensions/solr/
41

42. Custom templates
Use templates for a custom extension
42

43. Using FLUID rootPaths
• FLUID supports fallbacks:
plugin.tx_solr.view {
partialRootPaths {
0 = EXT:solr/Resources/Private/Partials/
100 = EXT:myextension/Resources/Private/Partials/
}
templateRootPaths {
0 = EXT:solr/Resources/Private/Templates/
100 = EXT:myextension/Resources/Private/Templates/
}
}
• See also: https://www.fiedomedia.de/news/artikel/template-fallbacks-in-typo3-fluid/
43

44. Custom facet partials
How to render facets in a custom partials
44

45. Use custom facet partial
Change the partialName to „Custom“ in TypoScript:
plugin.tx_solr.search.faceting.facets {
category {
label = Category
field = keywords_stringM
type = options
partialName = Custom
}
}
Copy the default partial „Options.html“ to
„Custom.html“
Use the core ViewHelper to make the option uppercase:
{option.label} => <f:format.case value="{option.label}" mode="upper"/>
