Not getting Snippet field in the Document object which is required for Search Summary purpose

Issue

• Snippet field doesn't get returned after using SearchRequestBuilderFactory to create the Search Request following Liferay's official documentation.

Environment

• DXP 7.4

Resolution

• In order to get a summary, the below code is suggested by https://help.liferay.com/hc/en-us/articles/360032611211-Returning-Results#creating-a-results-summary:

Summary summary = new Summary(
document.get(prefix + titleField, titleField),
document.get(prefix + contentField, contentField));
Here, the prefix is :-
String prefix = Field.SNIPPET + StringPool.UNDERLINE;

 

• The goal would be to generate the exact same thing that is shown here: https://learn.liferay.com/w/dxp/using-search/search-pages-and-widgets/search-results/search-results#result-summaries.
• Your code might look like this:

...

SearchResponse searchResponse = searcher.search(searchRequest);

SearchHits searchHits = searchResponse.getSearchHits();

List<SearchHit> searchHitsList = searchHits.getSearchHits();

for (SearchHit hit : searchHitsList) {

 Document document = hit.getDocument();

...

 

• But in order to achieve this goal, you must use the SearchResponse function getDocuments71(). This function will return a list of documents that contains the snippet title field and the snippet content field. The code example below may be useful:

 

...
SearchResponse searchResponse = searcher.search(searchRequest);

List<Document> documents = searchResponse.getDocuments71();

for (Document document : documents) {
...
