MongoDB allows you search for a word in the database

db.articles.find( { $text: { $search: "coffee" } } )

There doesn't seem to be an equivalent in matlab's interface to MongoDB.

Any thoughts on how to search for a string in the database?

在 MATLAB Online 中打开

Make sure you have a proper installation of MongoDB and the corresponding support packages in matlab

To connect to an existing database here is the link to the documentation

To connect to an existing database

server = "dbtb01";
port = 27017;
dbname = "mongotest";
conn = mongo(server,port,dbname)

To execute a search query

collection = "employee";
mongoquery = '{"department":"Sales"}';
documents = find(conn,collection,'Query',mongoquery);

Thanks for your response. I was hoping to find a way that can actually search the database first for the occurrence of a text string, as opposed to pulling everything into matlab and then searching for a text string within a structure. It appears that MongoDB can search for a string within the database, but that not feature is not available in the matlab implementation.
