Text Filtering
You can search for resources based on their text fields in a similar way.
This example searches for all Sites where the name is "My Site".
List Sites > Which have name "My Site"
But when searching for text in resources, you likely will want to use partial text searches. For this you can add a lookup like contains.
Here, we search for all Sites where the Site name contains the word "School":
List Sites > Which contain the text "School" in their name
The contains lookup gets appended to the end of the field name with a double-underscore.
Double Underscores
Double underscores (__) get used in many of the following examples to separate field names from lookups and each other.
Pay close attention to how they are used to get a feel for how you can invent your own filters to perform powerful searches within the API.
