The full-text field search<\/em> allows you to look for a field anywhere in a webpage, be it the title, content, or the url of a webpage.<\/p>\n

A full-text search shall match whole words. For example, a full-text search on comments that contains \u201cperform search\u201d or \u201ctext search\u201d or \u201ctext\u201d will return a comment that contains \u201cI want to perform text search in AEM\u201d.<\/p>\n

To implement the same in AEM6<\/a>, I have used QueryBuilder<\/a> API which is a service for building Queries for searching the Java Content Repository and are easily extensible.<\/p>\n

Demostration with code:<\/strong><\/p>\n

Populate in a map all the predicates with the values.
\nFulltext contains the value of the searchKey<\/em> which will be searched in the url and the content of the cq:page<\/em>, under the specified path<\/em><\/p>\n

[java]<\/p>\n

String pageTitle, pagePath
\nMap params = [:]
\nparams["path"] = path
\nparams["type"] = "cq:Page"
\nparams["fulltext"] = searchKey
\nparams["orderby"] = "@jcr:score"<\/p>\n

[\/java]<\/p>\n

now use Query interface to create a query object that will in turn use builder object of Query Builder interface to build the query.<\/p>\n

[java]<\/p>\n

Query query = builder.createQuery(PredicateGroup.create(params), session)
\n\/\/for pagination
\nquery.setStart(startPage) \/\/ same as params["p.offset"] = startPage.toString()
\nquery.setHitsPerPage(offset) \/\/ same as params["p.limit"] = offset.toString()<\/p>\n

[\/java]<\/p>\n

searchResult<\/em> will contain the result of the JCR query. A hit<\/em> represents a single search result which is adapted to a page so as to fetch the page title and page url for display.<\/p>\n

[java]
\n SearchResult searchResult = query.result
\n Long totalHits = searchResult.getTotalMatches()
\n for (Hit hit : searchResult.hits) {<\/p>\n

Page page = hit.resource.adaptTo(Page)
\n pageTitle = page.title
\n pagePath = page.path
\n searchHit = new JSONObject()
\n searchHit.put("totalHits", totalHits)
\n searchHit.put("path", pagePath)<\/p>\n

if (!pageTitle) {
\n pageTitle = pagePath.substring(pagePath.lastIndexOf(‘\/’) + 1, pagePath.length())<\/p>\n

}
\n searchHit.put("title", pageTitle)<\/p>\n

resultArray.put(searchHit)
\n }
\n resultObject.put("data", resultArray)
\n return resultObject
\n[\/java]<\/p>\n

The desired output looks like below:<\/span>
\n\"Search<\/a>
\nThis much should be sufficient to design a working Site Search component<\/em> in AEM that performs\u00a0f<\/em>ulltext Search\u00a0<\/em>and displays paginated results. I will introduce advanced fulltext\u00a0<\/em>queries\u00a0in my forthcoming post.<\/p>\n

Stay tuned!<\/p>\n","protected":false},"excerpt":{"rendered":"
