About the Tutorials

• How to Build Applications with Atlas Search and Atlas App Services contains tutorials that describe how to use Atlas App Services and Atlas Search to build a search UI and add reverse search to your application.

• The How to Check for Null and Non-Null Values with Atlas Search tutorial describes how to add documents containing null values and create a dynamic index on the sample_mflix.users collection. The queries search the sample_mflix.users collection for null and non-null fields.

• The How to Paginate Query Results describes how to use $skip and $limit after the $search stage to paginate query results, and the SEARCH_META Aggregation Variable to return the total documents found.

The query searches the sample_mflix.movies collection for movie titles that contain the given term regardless if the term contains diacritics.

• The How to Run an Atlas Search Compound Geo JSON Query tutorial describes how to create an index on the sample_airbnb.listingsAndReviews collection and run a query that returns documents with the name, address, and property_type of each property within a specified polygon defined using coordinates. Atlas Search results reflect a preference for properties of type condominium, and each document in the result is assigned a relevance score, returned in order from highest to lowest.

• The How to Run Atlas Search Compound Queries with Weighted Fields tutorial describes how to create a dynamic index and run compound queries with custom scoring. The queries search the sample_mflix.movies collection and alter the relevance score of the documents in the result using constant, boost, and function options.

The queries search the sample_mflix.movies collection for full movie plots that contain a multilingual term.

• The How to Run Atlas Search Queries Against Objects in Arrays tutorial demonstrates how to index fields of type string inside an array of objects and run Atlas Search queries against the indexed fields.

• The How to Run Atlas Search Queries with a Date Range Filter tutorial describes how to create a dynamic index and run compound queries that use the range operator. The queries search the sample_mflix.movies collection for movies between a specified date range.

• The How to Run Atlas Search String Queries Against Date and Numeric Fields tutorial describes how to run queries against numeric and date fields using operators that support only string queries. The queries search for properties that were listed on certain dates and allow them to stay up to a certain number of days.

• The How to Use Autocomplete with Atlas Search tutorial describes how to create and query an Atlas Search index configured with an autocomplete field using the autocomplete operator. We will create the Atlas Search index on the sample_mflix.movies collection and index title field text values for autocompletion. We will run Atlas Search queries using the autocomplete operator to search the indexed field for a sequence of characters.

• The How to Use Facets with Atlas Search tutorial describes how to create an index with a facet definition for the sample_mflix.movies collection and run queries against the faceted fields for results grouped by values and ranges in the specified, faceted fields, including a count for each of those groups.
