Implementing a full-text search engine in MongoDB Atlas simply requiresclicking a button. The user goes to any cluster and selects the “Search” tab. From there, click on “Create Search Index” to launch the process. Once the index is created, you can use the $search operator to perfor...

TheLONGTEXTdata object is for use in extreme text string storage use cases. It is a viable option when theMEDIUMTEXTobject is not big enough. Computer programs and applications often reach text lengths in theLONGTEXTrange. These data objects can be as large as 4 GB (expressed as 2^32 -1...
Use method fulltext_index to enable indexing of a model. The default is to index all attributes but it is recommended to provide a list of attribute keys.A side effect of calling this method is, that MongoSphinx overrides the default of letting MongoDB create new IDs: Sphinx only allows ...
