Text Search Operators

Note
Views do not support text search.
Query Framework
Use the $text
query operator to perform text searches on a collection with a text index.
$text
will tokenize the search string using whitespace and most punctuation as delimiters, and perform a logical OR
of all such tokens in the search string.
For example, you could use the following query to find all stores containing any terms from the list “coffee”, “shop”, and “java”:
Use the $meta
query operator to obtain and sort by the relevance score of each matching document. For example, to order a list of coffee shops in order of relevance, run the following:

and $meta
operators, including restrictions and behavior, see:

projection operator
Aggregation Framework
When working with the Aggregation framework, use $match
with a $text
expression to execute a text search query. To sort the results in order of relevance score,use the $meta
aggregation operator in the $sort
stage [1].
For more information and examples of text search in the Aggregation framework, see Text Search in the Aggregation Pipeline.
[1] | The behavior and requirements of the $meta projection operator differ from that of the $meta aggregation operator. For details on the $meta aggregation operator, see the $meta aggregation operator reference page. |
