Alfresco API to run faceted search

amit_kapps — Wed, 17 Feb 2016 23:51:28 GMT

Hello,I'm using Alfresco community 5.x version and I'm wondering if There are REST or any other remote alfresco apis to be able to run Faceted search.I've seen some Restful apis to administer/manage some aspects of Faceted search viz : http://docs.alfresco.com/community5.0/references/RESTful-Facet.h

It appears to be the correct repository web script you are referring at.
For more details, take a look at - search.get.desc.xml, search.get.js inside alfresco-remote-api-*.jar at the location alfresco\templates\webscripts\org\alfresco\slingshot\search. This will give you more clear idea.

Hope this helps.

I finally figured out how to implement and integrate the faceted search into a custom UI. the same also works with share.

<ol>
<li>create model in model manager (no hyphens)
<ul>
<li>Indexing attribute:
 <li>String: list of values whole match
 <li>Date, Number: enhanced search
 </ul>

<li> For each type define the layout design - w/o this you wont be able to change type in share at least.
<li> In share/search manager create filters/facets for fields you're interested in
<li> Add a custom *context.xml to define a bean with your custom FacetQueryProvider implementation. inject that into the facet.solrFacetHelper bean
<li> The custom FacetQueryProvider e.g. DollarAmountDisplayHandler basically provides facet queries based on the dollar amount buckets bean in the *context.xml, those will then be passed to solr.
<li> Jar up the FacetQueryProvider implementation and copy to tomcat/lib directory.
</ol>
