📄️ 📘 Intro to Search Operators
In the previous exercise, you used a $search stage that looked like this one.
📄️ 📘 The text Operator
The text operator is used to perform a full-text search using the analyzer that you specify in the index configuration. It is used to search for words or phrases in the full-text fields of your documents.
📄️ 📘 The phrase Operator
The phrase operator is used to search for a group of words in a specific order. It is similar to the match operator, except that it will match anywhere in the text, not just at the beginning.
📄️ 📘 The equals Operator
The equals operator is used to search for a specific value in a field. It is similar to the match operator, but the operation will be performed by Lucene and can be combined with other operators to refine results.
📄️ 📘 The range Operator
The range operator is similar to equals but works on ranges of values.
📄️ 📘 Scoring
You might have noticed that most of the operators have a score property, which we haven't really talked about so far.
📄️ 📘 Score Modifiers
In the operators you've seen so far, you can adjust the score property to modify the score of a result. This is useful for boosting or demoting results based on certain criteria.
📄️ 📘 Mixing and Matching
The whole value of using these operators comes from combining them to create search results that are more relevant to your users.
