The following tutorials take you through the steps of setting up and querying an Atlas Search index.
To complete these tutorials, you must have the following:
The How to Use Autocomplete with Atlas Search tutorial describes how to create and query an Atlas Search index configured with an
autocompletefield using the
autocompleteoperator. We will create the Atlas Search index on the
sample_mflix.moviescollection and index
titlefield text values for autocompletion. We will run Atlas Search queries using the
autocompleteoperator to search the indexed field for a sequence of characters.
The How to Run 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.moviescollection and alter the relevance score of the documents in the result using
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
rangeoperator. The queries search the
sample_mflix.moviescollection for movies between a specified date range.
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 a Compound Geo JSON Query tutorial describes how to create an index on the
sample_airbnb.listingsAndReviewscollection and run a query that returns documents with the
property_typeof 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 Use Facets with Atlas Search tutorial describes how to create an index with a facet definition for the
sample_mflix.moviescollection 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.
The How to Run Partial Match Atlas Search Queries tutorial describes how to create an index on the
sample_mflix.moviescollection and run case-sensitive partial match queries against the indexed field using autocomplete, phrase, regex, and wildcard operators.
The How to Use Synonyms with Atlas Search tutorial describes how to add a collection that configures words as synonyms, create an index that defines synonym mappings on the
sample_mflix.moviescollection, and run Atlas Search queries against the
titlefield using words that are configured as synonyms.
The How to Run Multilingual Atlas Search Queries tutorial describes how to create an index that uses a language analyzer and perform a multilingual search against the
sample_mflix.moviescollection. The queries search the
sample_mflix.moviescollection for full movie plots that contain a multilingual term.
The How to Define a Custom Analyzer and Run a Diacritic-Insensitive Query tutorial describes how to create an index that uses a custom analyzer and perform a diacritic-insensitive search against the
sample_mflix.moviescollection. The query searches the
sample_mflix.moviescollection for movie titles that contain the given term regardless if the term contains diacritics.
The How to Sort Your Atlas Search Results for Your Perfomance Needs tutorial describes how to index and store fields on
mongotfor interim operations such as sort, run queries against the indexed fields, and then sort the results on the returned fields using
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 Run Queries Across Collections contains tutorials that describe how to run queries across multiple collections by first combining collections using materialized views,
$unionWith, and then running
$searchqueries against the collections.
