Goal
Add an Assets search rail predicate to search using jcr:uuid (index available otb /oak:index/uuid)
Query executed is something like below
/jcr:root/content/dam/texas//element(*, dam:Asset)[(@jcr:uuid = 'e164529c-2ea2-4925-9ad5-0c443ec57ee3')]

Asset ID Filter in Rail
Assets Search form Configuration
http://localhost:4502/libs/cq/core/content/tools/customsearch.html/libs/settings/dam/search/facets/assets/jcr:content
Solution
1) Login to CRXDe Lite and add the Asset ID predicate configuration eaemjcruuid in /apps/settings/dam/search/facets/formbuilderconfig/predicatetypes/items
2) Create the configuration page for predicate (fieldPropResourceType in step 1) /apps/eaem-search-form-jcruuid-predicate/jcruuid-field/jcruuid-field.jsp with the following code
3) Create the predicate widget render html (fieldResourceType in step 1) /apps/eaem-search-form-jcruuid-predicate/jcruuid-predicate/jcruuid-predicate.jsp with following code
4) Add the predicate evaluator apps.experienceaem.assets.JcrUUIDPredicateEvaluator for searching using jcr:uuid

2) Create the configuration page for predicate (fieldPropResourceType in step 1) /apps/eaem-search-form-jcruuid-predicate/jcruuid-field/jcruuid-field.jsp with the following code
<%@include file="/libs/granite/ui/global.jsp" %>

3) Create the predicate widget render html (fieldResourceType in step 1) /apps/eaem-search-form-jcruuid-predicate/jcruuid-predicate/jcruuid-predicate.jsp with following code

String selected = foldableOpen ? "selected":"";
AttrBuilder inputAttrs = new AttrBuilder(request, xssAPI);
inputAttrs.add("type", "text");
inputAttrs.add("name", metaType);
inputAttrs.addClass("coral-Form-field coral-Textfield coral-DecoratedTextfield-input");

4) Add the predicate evaluator apps.experienceaem.assets.JcrUUIDPredicateEvaluator for searching using jcr:uuid
