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.
