The sample reads the Spring IO blog Atom feed and performs text search on it. We use manual index creation and query via MongoTemplate as well as automatic index creation and derived queries via repositories. Original pull request: #10.

Spring Data MongoDB - Text Search Examples
This project contains samples of text search specific features of Spring Data Mongodb.
Support for Text Index
Define text index structures manually (like below) or use @TextIndexed to mark content to be indexed for full text search.
TextIndexDefinition textIndex = new TextIndexDefinitionBuilder()
.onField("title", 3F)
.onField("content", 2F)
.onField("categories")
.build();
template.indexOps(BlogPost.class).ensureIndex(textIndex);
Support for full text repository queries
Use derived finder methods to search for terms and phrases.
interface BlogPostRepository extends CrudRepository<BlogPost, String> {
// page through results for full text query
Page<BlogPost> findBy(TextCriteria criteria, Pageable page);
// find all matching documents and sort by relevance
List<BlogPost> findAllByOrderByScoreDesc(TextCriteria criteria);
}
