MongoDB text search

The mongodb $text operator performs a text search on the content with a text index and returns all the documents that match search text.

Syntax:

{

  $text: {$search: <string>, $language: <string>, $caseSensitive: <boolean>,

      $diacriticSensitive: <boolean>}

}

In the above, the text search operator’s language, caseSensitive and diacriticSensitive are optional but search is required.

Query Restrictions

• The $text query can perform at least one $text expression.
• The $text query can’t appear in $nor expressions.
• We can use a $text query in an $or expression but all the clauses in the $or must be indexed.
• If the your query includes a $text expression that time you can’t use hint() function.
• You cannot specify $natural sort order if the query includes a $text expression etc.

Query: db.customers.find( { $text: { $search: "mongodb collection text" } } )
